Help build AeroPrep
AeroPrep is an independent project and there is a lot we still want to do. If you can help with any of these, or have a better idea, we would love to hear from you.
Run code for real
The coding round is judged by the AI. Running solutions against test cases in a sandbox would make the result exact.
A more human voice
Alex speaks with the browser's built-in voice. A proper text-to-speech voice would make the interview feel far more real.
Faster replies
Streaming Alex's answer as it is written, and speaking it sentence by sentence, would cut the pause after each answer.
More kinds of interview
System design rounds, behavioural-only rounds, and tracks for data, product and DevOps roles.
Company-style interviews
Question styles modelled on how specific companies interview, such as leadership-principle rounds.
Progress over time
Charts of your scores across interviews and the weaknesses that keep coming up.
