Sharing my quick personal anecdote here.
- Past: ~8 years in big tech as an IC - Currently: ~4 as CTO a < 10 person startup.
I always hated doing and conducting coding interviews. When I became in charge of the interview process, I swore to myself not to have them.
I had to let go of a person after ~3 weeks in because he just didn't write any code. This was about 1 year post the ChatGPT moment.
He had lots of experience. Great communicator. Culture fit (or so I thought). Etc...
Interviews can provide a signal, but nothing trumps a month of working with someone. If both parties are open to it, a well paid short term contracting gig goes a long way.
