  • Strong judgment when working with financial transactions, including knowing when not to execute a transaction and using dry runs when appropriate.
  • Strong testing practices and experience treating automated tests as part of the development process.
  • Ability to take ownership of production systems and troubleshoot issues independently.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
