Austen McDonald led mobile hiring at Meta and was on hundreds of hiring committees during his time there. I asked him about what goes on behind the scenes for senior+ eng hiring and how to succeed on behavioral interviews. We discussed: • How unethical/lying candidates are caught • How to avoid downleveling • How leveling works and if you can negotiate level mid-process • How behavioral interviews are scored • How referrals work in the hiring process • Company specific value prep at OpenAI/Anthropic I always felt like behavioral interviews were less concrete than technical interviews as an engineer so I was also curious about subjectivity and bias.

It did feel a bit wasteful in terms of eng time to need two people to do similar work because of mobile platform fragmentation It's a good thing but also in the limit, wonder if product feature team sizes get cut in ~half to do the same work

It's common for product feature teams to have 1 iOS and 1 Android eng assigned to a project basically implementing the same thing I imagine that work is easily handled by 1 eng powered by Claude Code/Codex these days E.g. how OpenAI built Sora for Android (below)

"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 ( @attwellbrian ) 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 𝗣𝗼𝗱𝗰𝗮𝘀𝘁 𝗹𝗶𝗻𝗸𝘀: • Transcript: developing.dev/p/uber-disting… • Youtube: youtu.be/egNtHu4q-vI • Spotify: open.spotify.com/episode/4aoQ2l… • Apple: podcasts.apple.com/au/podcast/the…

Interviewed the CTO of Atoms a few months ago where he shared his full career story. This mindset of pushing through the pain was clear there as well (link in the reply if you're curious)

@yongsen_teo Makes sense, thank you for the input. It seems the incremental benefit of sharing the full thing here is marginal Main argument I see for posting here is if the algo somehow boosts longer videos, will experiment YouTube + Spotify links will still be there

Episode launching tomorrow morning: Distinguished Eng career story and tech lead working on Codex at OpenAI He's the type of engineer that has a ton of impact through the code he writes rather than being an uber tech lead (tech lead among tech leads) Aside from his career story, it was also interesting to hear his unique perspective on how tools like Codex have been changing software engineering for him. For instance I asked: • What problems are best for the model vs what code does he still choose to write manually? • What programming knowledge still matters given the rapid advancement of agentic tools? He was a dream guest of mine and I'm super excited to share his story with you all, episode dropping here tomorrow morning!
