BreakCareerPattern.com // I help people stuck in underpaid/stagnant jobs land their Dream Job

When I began my career I faced 24 straight interview rejections, which crushed my confidence. People around me blamed my attitude, and I ended up working part-time, wondering if this was my future.

Then I got a job in Amazon's customer support but felt stuck and uninspired. That changed when I met an Oxford MBA who landed multiple interviews within minutes and revealed his secret: Networking.

Inspired, I created a group of people to crack the code on job hunting. Soon, I secured offers from Google and American Express, landing my dream role at Amex with a 230% salary increase—all without an MBA.

✅ Today, I teach people (just like you!) how to use the same process to land their dream job even without the "right" experience on paper.

✨Now, I help others achieve similar results with my proven job search process, which has led thousands to jobs at top companies like Google, Amazon, PWC, Microsoft, IBM, General Electric, Bain & Company, American Express, Samsung, JP Morgan & more. 

My clients don’t just get offers—they enjoy:

•  💰 100% Average Salary Boost
•  📞 6 Months of Career Mentoring
•  🎯 100% Career Satisfaction
•  📶 100X ROI on Investment

Ready to land multiple dream job offers?

Don't just take my word for it though. Here's what a few of my clients have to say about working with me:

"Rajeev also helped me navigate the often challenging task of salary negotiation. His techniques gave me the confidence to assert my worth, resulting in a 45% increase in my compensation along with additional benefits like remote work flexibility. " - David 

"With his guidance, I not only gained confidence but also started receiving responses and interview opportunities from top companies. Thanks to the strategies and tactics I learned, I eventually landed a dream role in the banking sector—something I once thought was out of reach." - Prajuna

" Rajeev's deep understanding of career dynamics and his ability to provide tailored advice set him apart. Without the need for cohort certifications or structured programs, he helped me leverage my existing skills and experiences to successfully transition into a new field." - Hardi

If I had to learn Python for Data Science in 60 days, this is the roadmap I'd follow.

(Most people overcomplicate this. Don't)

You don't need to master everything. You need to master what matters for data roles. Here's the exact path:

𝐖𝐞𝐞𝐤 𝟏-𝟐: 𝐏𝐲𝐭𝐡𝐨𝐧 𝐅𝐮𝐧𝐝𝐚𝐦𝐞𝐧𝐭𝐚𝐥𝐬
↳ Variables, data types, loops, conditionals
↳ Functions and lambda expressions
↳ List comprehensions

𝐖𝐞𝐞𝐤 𝟑: 𝐂𝐨𝐫𝐞 𝐃𝐚𝐭𝐚 𝐒𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞𝐬
↳ Lists, dictionaries, sets, tuples
↳ When to use each one
↳ This is your foundation

𝐖𝐞𝐞𝐤 𝟒-𝟓: 𝐄𝐬𝐬𝐞𝐧𝐭𝐢𝐚𝐥 𝐋𝐢𝐛𝐫𝐚𝐫𝐢𝐞𝐬
↳ NumPy for numerical operations
↳ Pandas for data wrangling (spend extra time here)
↳ Matplotlib & Seaborn for visualization

𝐖𝐞𝐞𝐤 𝟔: 𝐒𝐭𝐚𝐭𝐢𝐬𝐭𝐢𝐜𝐬 & 𝐄𝐃𝐀
↳ Mean, median, mode, standard deviation
↳ Correlation and distributions
↳ Exploratory data analysis techniques

𝐖𝐞𝐞𝐤 𝟕-𝟖: 𝐌𝐋 𝐁𝐚𝐬𝐢𝐜𝐬 & 𝐏𝐫𝐨𝐣𝐞𝐜𝐭𝐬
↳ Scikit-learn fundamentals
↳ Data preprocessing and cleaning
↳ Build 2-3 projects to solidify everything

The key is to code every single day. Even 30 minutes of hands-on practice beats 3 hours of passive learning.

I just got back from San Francisco.

And I'm still processing what happened. I left with some of the best memories of my life.

𝐌𝐚𝐧𝐢𝐟𝐞𝐬𝐭 𝐆𝐚𝐥𝐚 brought together some of the most incredible people I've ever met in one room. Creators, founders, and attendees with O1s and EB1s. People building real things.

But here's what hit me the hardest:

𝐓𝐡𝐞 𝐩𝐨𝐰𝐞𝐫 𝐨𝐟 𝐢𝐧-𝐩𝐞𝐫𝐬𝐨𝐧 𝐜𝐨𝐧𝐧𝐞𝐜𝐭𝐢𝐨𝐧𝐬 𝐢𝐬 𝐮𝐧𝐦𝐚𝐭𝐜𝐡𝐞𝐝.

I finally met Deedy Das and Marina Mogilko. I've watched almost every one of Marina's podcasts. Following her content for so long, and then actually meeting her in person? Surreal.

I met the Tech Roast Show crew. Been watching them roast tech people forever. Now we were in the same room laughing together.

But what made this trip unforgettable was the 2 days I spent with fellow creators:

↳ Ferry rides across the bay
↳ Getting to know each other beyond the content
↳ Playing Mafia until 3 AM (I found out I absolutely suck at it. I cannot lie.)
↳ Late-night food runs
↳ Conversations about personal journeys, professional struggles, and everything in between

From Thursday to Saturday, most of us barely slept 4 hours a day.

And honestly? Some of the best days of my life.

You can DM someone for months. Comment on their posts. Engage with their content.

But nothing compares to being in the same room. Sharing a meal. Laughing at 3 AM over a game you're terrible at.

If you ever get the chance to show up in person, take it.

The connections you make will change everything.

So glad that I got to meet you all: Pritesh, Vishakha, Sohan, Varun, Roshni Chellani, Shreya, Sriram, Chintan, Amulya, Muskan, Jugal, Shreya, Narayan and more! You guys are the best!!

The H-1B lottery rejected me twice.

AWS has 200+ services. Most data professionals only need 15.

(Once you know these, AWS stops feeling overwhelming)

I've seen too many people bounce between random tutorials and give up halfway. The problem isn't AWS. It's not having a mental model.

Most data systems, no matter how complex, are built on just five layers:

Storage → Processing → Analytics → Machine Learning → Security

Once that clicks, everything becomes logical.

Here are the 15 AWS services every Data Analyst and Data Scientist should know:

𝐒𝐭𝐨𝐫𝐚𝐠𝐞 & 𝐃𝐚𝐭𝐚 𝐋𝐚𝐤𝐞𝐬
↳ S3: Your data lake foundation. Raw files, CSVs, Parquet - everything starts here.
↳ RDS: Managed PostgreSQL/MySQL for relational workloads.
↳ Redshift: Cloud data warehouse for SQL on massive datasets.

𝐃𝐚𝐭𝐚 𝐏𝐫𝐨𝐜𝐞𝐬𝐬𝐢𝐧𝐠 & 𝐄𝐓𝐋
↳ Glue: Serverless ETL across sources.
↳ Athena: Query S3 directly with SQL. No infrastructure.
↳ EMR: Spark and Hadoop for large-scale processing.
↳ Lambda: Event-driven compute for pipeline automation.

𝐀𝐧𝐚𝐥𝐲𝐭𝐢𝐜𝐬 & 𝐁𝐈
↳ QuickSight: Native BI for dashboards and visualizations.

𝐌𝐚𝐜𝐡𝐢𝐧𝐞 𝐋𝐞𝐚𝐫𝐧𝐢𝐧𝐠
↳ SageMaker: End-to-end ML platform for building and deploying models.
↳ Bedrock: Access foundation models like Claude and Llama.
↳ Comprehend: NLP insights from text without custom models.

𝐒𝐭𝐫𝐞𝐚𝐦𝐢𝐧𝐠 & 𝐑𝐞𝐚𝐥-𝐓𝐢𝐦𝐞
↳ Kinesis: Ingest and process streaming data.

𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 & 𝐀𝐜𝐜𝐞𝐬𝐬
↳ IAM: Define who can access what.
↳ KMS: Manage encryption keys.
↳ Secrets Manager: Store and rotate API keys and credentials.

𝐒𝐭𝐚𝐫𝐭𝐢𝐧𝐠 𝐨𝐮𝐭? 𝐅𝐨𝐥𝐥𝐨𝐰 𝐭𝐡𝐢𝐬 𝐩𝐚𝐭𝐡:

S3 → Athena → Glue → Redshift → SageMaker

Master this flow and you'll understand how most modern data platforms on AWS are built.

90% of SQL interviews test the same 10 window functions.

(If you know them, you're already ahead)

Most analysts write 15-line subqueries for problems that window functions solve in 3 lines. Interviewers notice.

Here are the 10 SQL window functions every data analyst and data scientist should know:

𝟏. 𝐑𝐎𝐖_𝐍𝐔𝐌𝐁𝐄𝐑()
↳ Assigns a unique sequential number to each row
↳ Use it for: deduplication, pagination, finding first/last records per group

𝟐. 𝐑𝐀𝐍𝐊()
↳ Ranks rows with ties getting the same rank, leaves gaps after
↳ Use it for: leaderboards, finding top N with ties

𝟑. 𝐃𝐄𝐍𝐒𝐄_𝐑𝐀𝐍𝐊()
↳ Ranks rows without leaving gaps, even with ties
↳ Use it for: ranking when you need consecutive numbers

𝟒. 𝐋𝐀𝐆()
↳ Returns the value from the previous row
↳ Use it for: day-over-day changes, comparing to previous period

𝟓. 𝐋𝐄𝐀𝐃()
↳ Returns the value from the next row
↳ Use it for: forecasting, calculating time between events

𝟔. 𝐒𝐔𝐌() 𝐎𝐕𝐄𝐑
↳ Calculates running or cumulative totals
↳ Use it for: running revenue, cumulative user growth

𝟕. 𝐀𝐕𝐆() 𝐎𝐕𝐄𝐑
↳ Computes moving or rolling averages
↳ Use it for: 7-day rolling averages, smoothing trends

𝟖. 𝐍𝐓𝐈𝐋𝐄()
↳ Divides rows into N equal groups
↳ Use it for: quartiles, percentiles, bucketing users

𝟗. 𝐅𝐈𝐑𝐒𝐓_𝐕𝐀𝐋𝐔𝐄()
↳ Fetches the first value in an ordered window
↳ Use it for: first purchase date, earliest event per user

𝟏𝟎. 𝐋𝐀𝐒𝐓_𝐕𝐀𝐋𝐔𝐄()
↳ Fetches the last value in an ordered window
↳ Use it for: most recent activity, latest status per group

I've seen these exact functions show up in take-home assignments at Google, Meta, and Amazon. Master them before your next interview.

SQL window functions

You can't analyze data you don't have.
You can't model the data you don't have.
You can't make decisions with data you don't have.

Here's how to get it.

The best datasets aren't on Kaggle.
They're not waiting in your company's database.
They're sitting on websites - unstructured and untouched.

Job listings. Product prices. Competitor intel. Customer reviews.

This is the data that actually moves the needle. And it's not coming to you in a clean CSV.

Building scrapers from scratch with BeautifulSoup or Selenium?

Great for learning. Painful at scale.

You end up managing proxies, CAPTCHAs, anti-bot detection, JavaScript rendering, and constant maintenance when sites change.

The faster path? Use a scraping API.

You send a URL + parameters. It handles everything and returns structured data.

I've been using 𝐎𝐱𝐲𝐥𝐚𝐛𝐬 Web Scraper API.

𝐖𝐡𝐲 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬:
↳ Handles IP blocks and CAPTCHAs automatically
↳ Returns clean JSON, no parsing headaches
↳ Works on Amazon, Google, job boards, any public site
↳ You only pay for successful results

You spend hours perfecting your resume. Send it to dozens of companies. And still get ghosted.

Not because you're not qualified.

But because you're playing the same game as everyone else.

While others attach PDFs, what if you sent a personalized pitch deck instead?

𝐇𝐞𝐫𝐞'𝐬 𝐰𝐡𝐚𝐭 𝐢𝐭 𝐝𝐨𝐞𝐬:

→ Reads your resume and the job description 
→ Matches your skills to their exact requirements 
→ Builds a professional pitch deck tailored to that role 
→ Ready to send in under 60 seconds

No code. No API keys. No automation tools. Just a chat window.
You copy a prompt. You paste it. You get a deck.

And this is just one workflow. Gamma now connects to ChatGPT, Gmail, HubSpot, Zapier, Clay, and more. 700K+ presentations are created in Gamma every single day.

Comment "𝐆𝐀𝐌𝐌𝐀" and I'll send you:
→ Step-by-step setup guide (takes 2 minutes)
→ The exact master prompt that builds your deck
→ 3 recruiter message templates to actually send the deck

Stop getting ghosted. Start getting callbacks.

Most job seekers waste 80% of their time on the wrong job boards.

By the time you see it on job boards, hundreds have already applied.

I've been testing a tool that honestly feels like cheating (the good kind): 𝐉𝐨𝐛𝐂𝐨𝐩𝐢𝐥𝐨𝐭.

𝐖𝐡𝐚𝐭 𝐢𝐭 𝐚𝐜𝐭𝐮𝐚𝐥𝐥𝐲 𝐝𝐨𝐞𝐬:
↳ Monitors 500,000+ company career pages 24/7
↳ Finds jobs before they hit the mainstream boards
↳ Auto-fills those mind-numbing application forms
↳ Answers screening questions in your voice
↳ Tracks everything so you never lose an application
↳ Automatically finds emails and LinkedIn of Hiring Managers (New Feature)

𝐓𝐡𝐞 𝐫𝐞𝐚𝐥 𝐤𝐢𝐜𝐤𝐞𝐫:
While you're sleeping, it's applying. While you're networking, it's applying. While you're prepping for interviews, it's still applying.

One candidate told me they got 5 interviews in their first week. Not because they're special. Because they applied to jobs nobody else had seen yet.

Start using JobCopilot here: https://lnkd.in/dEVsCgSA

While JobCopilot handles the heavy lifting, you focus on what humans do best:
↳ Building genuine connections
↳ Perfecting your interview skills
↳ Networking at events
↳ Preparing killer presentations

Your competition is still copying and pasting into the same forms. You could be getting callbacks from jobs they haven't even found yet.

Stop playing the numbers game manually when AI can play it better.

1,300 applications. That's how many it took me to land my first job.

Most of that time? Wasted on the wrong things.

I spent 80% of my energy filling out forms, tracking spreadsheets, and refreshing my inbox. The stuff that actually moves the needle, networking, interview prep, and coffee chats, got maybe 20%.

The applications aren't the hard part. Getting them done efficiently is.

I've seen job seekers reclaim their time and land interviews faster because JobCopilot takes care of the heavy lifting behind the scenes.

Leaving space for what actually moves the needle:
↳ Networking with intent
↳ Practicing for interviews
↳ Having those coffee chats that turn into referrals

Your next offer could be sitting in one of those auto-filled applications.

It's like having a 24/7 job-hunting assistant that never sleeps.

The H-1B lottery rejected me.

I thought I'd have to leave the country.

(If this is your story, keep reading.)

The H-1B lottery closes in 6 days. Thousands of immigrants are about to face the same uncertainty: stay, leave, or find alternatives.

There is an alternative. The O-1 Visa.

No lottery. No cap. No random draw.

You need to meet 3 out of these 8 criteria:

1. 𝐀𝐰𝐚𝐫𝐝𝐬 - Recognition for excellence
2. 𝐌𝐞𝐦𝐛𝐞𝐫𝐬𝐡𝐢𝐩𝐬 - Selective, invitation-based groups
3. 𝐏𝐮𝐛𝐥𝐢𝐬𝐡𝐞𝐝 𝐖𝐨𝐫𝐤 - Your contributions shared publicly
4. 𝐉𝐮𝐝𝐠𝐢𝐧𝐠 - Reviewing others' work
5. 𝐎𝐫𝐢𝐠𝐢𝐧𝐚𝐥 𝐖𝐨𝐫𝐤 - Innovative contributions with impact
6. 𝐌𝐞𝐝𝐢𝐚 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬 - Coverage in credible outlets
7. 𝐇𝐢𝐠𝐡 𝐒𝐚𝐥𝐚𝐫y - Top-tier earnings in your field
8. 𝐂𝐫𝐢𝐭𝐢𝐜𝐚𝐥 𝐑𝐨𝐥e - Key, high-impact positions

Most tech professionals already meet several of these. They just haven't documented them properly.

𝐌𝐚𝐧𝐢𝐟𝐞𝐬𝐭 𝐋𝐚𝐰 helps turn your existing achievements into a strong O-1 case.

That hackathon win? Counts.
Your tech blog? Counts.
Leading that critical project? Counts.

The H-1B lottery closes March 19. Start building your backup plan now. 

I got mine picked on my second attempt. I hope you get yours too. But if you don't, just know there are other paths forward.

All the best, everyone.

I just analyzed 2 months of my Instagram data in 45 minutes. 5 insights I wish I knew sooner.

No SQL. No Python. Just plain English questions.

It's an open-source AI analyst system built on Claude Code - 18 specialized agents, 39 skills, all markdown. 

You connect your data, ask a business question, and it frames it, explores your data, finds the root cause, builds a narrative, and hands you a branded slide deck with speaker notes.

𝐇𝐞𝐫𝐞'𝐬 𝐰𝐡𝐚𝐭 𝐢𝐭 𝐟𝐨𝐮𝐧𝐝:

1. 𝐃𝐚𝐭𝐚 𝐒𝐜𝐢𝐞𝐧𝐜𝐞 𝐑𝐞𝐞𝐥𝐬 = 𝐦𝐲 𝐞𝐧𝐠𝐚𝐠𝐞𝐦𝐞𝐧𝐭 𝐞𝐧𝐠𝐢𝐧𝐞
↳ 8% average engagement rate (highest on my account)
↳ 406 new followers per post

2. 𝐉𝐨𝐛 𝐒𝐞𝐚𝐫𝐜𝐡 𝐑𝐞𝐞𝐥𝐬 = 𝐦𝐲 𝐯𝐢𝐫𝐚𝐥 𝐫𝐞𝐚𝐜𝐡 𝐞𝐧𝐠𝐢𝐧𝐞
↳ 187K average views per post
↳ 3x more reach than anything else
↳ One post hit 700K views

3. 𝐏𝐞𝐫𝐬𝐨𝐧𝐚𝐥 𝐒𝐭𝐨𝐫𝐲 𝐂𝐚𝐫𝐨𝐮𝐬𝐞𝐥𝐬 = 𝐜𝐮𝐭𝐭𝐢𝐧𝐠 𝐭𝐡𝐞𝐦 𝐢𝐦𝐦𝐞𝐝𝐢𝐚𝐭𝐞𝐥𝐲
↳ 44 saves per post (1/40th of Job Search content)
↳ Not worth the production time

4. 𝐍𝐞𝐯𝐞𝐫 𝐩𝐨𝐬𝐭 𝐨𝐧 𝐓𝐡𝐮𝐫𝐬𝐝𝐚𝐲𝐬
↳ 27K reach on Thursdays vs 140K on Wednesdays
↳ Same content. Completely different results.

5. 𝐏𝐞𝐫𝐬𝐨𝐧𝐚𝐥 𝐒𝐭𝐨𝐫𝐲 𝐑𝐞𝐞𝐥𝐬 = 𝐔𝐒 𝐚𝐮𝐝𝐢𝐞𝐧𝐜𝐞 𝐦𝐚𝐠𝐧𝐞𝐭
↳ 56% US viewers on average
↳ Critical for brand deals and course sales

𝐒𝐦𝐚𝐥𝐥 𝐬𝐚𝐦𝐩𝐥𝐞 𝐜𝐚𝐯𝐞𝐚𝐭: Two months of data means these are directional signals, not statistically proven conclusions. But the patterns are clear enough to act on.

This kind of analysis would have taken me days. It took 45 minutes.

My content team (Muskan Agarwal, Cherry Media) is already using this report to plan next month's content.

Thanks for building this, Shane, Sravya, and Hai. They're also running a free session tomorrow on analyzing product data with Claude Code.

The most common DM I've gotten this month isn't just about data analytics.

It's "How do I break into cybersecurity?"

I'm not a cybersecurity expert. But I know what it's like to start from zero in a completely new field.

I switched from electrical engineering to data science while moving to a different country. No background. No connections. Just a decision to figure it out.

So when people kept asking, I did what I always do: I researched the best starting point.

That's how I found 𝐓𝐫𝐲𝐇𝐚𝐜𝐤𝐌𝐞.

𝐖𝐡𝐚𝐭 𝐢𝐦𝐦𝐞𝐝𝐢𝐚𝐭𝐞𝐥𝐲 𝐬𝐭𝐨𝐨𝐝 𝐨𝐮𝐭:
↳ 100% hands-on, browser-based labs (no downloads, no setup)
↳ Zero multiple-choice questions
↳ Learn by actually doing the work, not memorizing theory

Over 6.5 million people are already learning on it. There's a reason for that.

And if you get stuck, there's 𝐄𝐜𝐡𝐨, TryHackMe's AI tutor available 24/7. It doesn't just give you answers. It walks you through the thinking and helps you actually understand. For someone starting from zero, that's huge.

You can start completely free. But if you're serious about building a career in cyber, Premium unlocks everything: all learning paths, faster lab machines, and certification prep.

If you've been sitting on the question "where do I even start?" this is your answer.

No expensive equipment. No CS degree. Just an internet connection and the willingness to start.

♻️ Repost if someone in your network has been asking about breaking into cyber.

The hardest part of being an immigrant in tech isn't the visa.

It's the culture and the communication.

I often hear from data analysts and scientists asking how to ace interviews, land jobs, or make a career shift. Most of them have the technical skills locked down – SQL, Python, stats. All solid.

But here's what holds them back:

↳ They freeze up explaining their analysis in meetings
↳ They nail the technical round but stumble in behavioral interviews
↳ They have the answer, but stay quiet because they're not confident speaking up
↳ Stakeholders keep asking, "Can you repeat that?"

Sound familiar?

Technical skills get you the interview. Clear communication gets you the job.

That's why I recommend ELSA, Corp  Speak to anyone in my community who's working on this.

𝐖𝐡𝐚𝐭 𝐢𝐭 𝐢𝐬:
A Google-backed AI speaking coach (celebrating 10 years) that gives you real-time feedback on your pronunciation and clarity.

𝐖𝐡𝐲 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬 𝐟𝐨𝐫 𝐝𝐚𝐭𝐚 𝐩𝐫𝐨𝐟𝐞𝐬𝐬𝐢𝐨𝐧𝐚𝐥𝐬:

↳ 𝐏𝐫𝐨𝐧𝐮𝐧𝐜𝐢𝐚𝐭𝐢𝐨𝐧 𝐟𝐞𝐞𝐝𝐛𝐚𝐜𝐤
Identifies unclear sounds and stress patterns so you know exactly what to fix

↳ 𝐑𝐨𝐥𝐞𝐩𝐥𝐚𝐲 𝐜𝐨𝐧𝐯𝐞𝐫𝐬𝐚𝐭𝐢𝐨𝐧𝐬
Practice stakeholder meetings, interviews, and presentations with instant feedback

Think of it as a gym for your speaking skills. You wouldn't present a model without testing it. Don't present to leadership without practicing either.

𝐌𝐲 𝟐 𝐜𝐞𝐧𝐭𝐬:
Your SQL skills won't matter if you can't explain your insights clearly. The analysts getting promoted aren't just technically strong. They communicate with confidence.

Try ELSA and practice speaking regularly. There's a big discount through my link in the comments
