Software Engineering Intern

In 3 years at Instagram I got promoted from new grad (IC3) to staff engineer (IC6). I got lucky to have had such wonderful mentorship and aim to share that knowledge through my newsletter (www.developing.dev) to help others who don’t have access to similar resources. If you're a software engineer, you might be interested in subscribing.

Ryan Peterman

In Navdeep's (Neetcode) recent viral rant video, one of his points was that people don't think for themselves enough, and it holds them back.

It made me think of a small change I made that took me from getting rejected by every company during my senior year Leetcode interviews to getting offers from almost every company I interviewed at less than one year later (true story).

When I practiced my senior year, I did over 100 problems, but I'd keep pressing the "run tests" button and try to reverse engineer the answer from the tests I failed. Knowing I could short-circuit the thinking I needed to do really hampered my learning, and the results speak for themselves. I interviewed at a bunch of places (e.g., Two Sigma, Facebook, Google, etc) and failed every single one. The only one I passed was Amazon's, which wasn't even Leetcode at the time.

When I practiced again less than one year later to leave Amazon, I changed one simple thing. I set a 30-minute timer for each problem and didn't let myself look up the solution or press the "run tests" button before then. I did that so it'd be similar to the real interview environment, and it turned out that letting myself struggle also made me way better at Leetcode.

That recruiting season, I was surprised to see I got an offer from every company (e.g., Facebook, Google, Riot, Affirm, etc.) I interviewed at except for one (7 out of 8). Insane difference in results that I'd at least partially attribute to how I practiced. I remember Google's interviewer asking me if I thought the solution was correct, and I had a lot more confidence saying yes without a "run tests" button.

Anyway, the moral of the story is that although Neetcode's rant is a bit emotionally charged, I'll say it matches with my experience. If you want to get better at Leetcode, you need to let yourself struggle. It's similar to real software engineering. You have to find that sweet spot between letting yourself try solving the problem and asking for the answer from your more experienced teammates if you want to grow.

"If you want to be Senior Staff at one of the world's best tech companies by the time you're 25, this is the only way to do it"

Brian Attwell grew to Senior Staff at Uber by age 25. After that he left Uber to join CloudKitchens (Travis Kalanick’s current startup) and quickly became the CTO after his team doubled in size every 6 months. I asked him about how he did it. We discussed:

• His growth to Senior Staff at Uber
• Intelligence and interviewing
• How his team doubled every 6 months
• Brutally honest takes about Amazon and Google
• Travis Kalanick and Steve Jobs experiences
• Advice for his younger self

• Why being under leveled is a good thing
• The story behind his growth to Principal (IC8) at Meta
• Technical book that had the biggest impact on him as an engineer
• The most important principle in product engineering
• Claude Code stories & competition in AI coding products

Jayendra Jog (SWE turned $1B+ crypto founder): "People tend to be way too scared of leaving their jobs"

Jay left Robinhood after becoming jaded about software engineering career ladders to found his own company (Sei Labs). He raised $35m and the cryptocurrency backing his company grew to $2.7B at it's peak. I asked him about his non-linear career and what he learned along the way. We discussed:

• Getting promoted while coasting
• Learnings from raising $35m
• What founding taught him that engineering didn't
• Gamestop stories from the inside
• Big tech vs startup careers
• What benefit crypto provides the world for skeptics

Thought it'd be interesting to present some varied career stories instead of only the linear big tech career ladder ones. Let me know what you think!

Spent a few days curating some holiday gift inspiration focused on what you could buy that'd improve your quality of life

There's no affiliate links in the article (I don't benefit from any of these product recommendations)

Just something I thought would be fun and helpful if you're looking for a gift to buy this holiday season

Full of products I've personally used cross-referenced with a bunch of viral threads I found on Twitter. I love these products and think you will too:
