Athena's interview process for developers is very well thought out and is the best I've encountered during my career.

There is a phone screen before bringing you into the office for the in-person interviews.

In the office there are four interviews: two coding sessions and two personality sessions.

The coding problems were difficult enough to be challenging without relying on gotcha questions.

The personality interviews are conversations to see if you're a good fit for the company, and to see if the company culture is a good fit for you.

Describe one time where you had to debug a difficult technical problem, and how did you solve it.
