I put up a sparse profile on LinkedIn and was contacted within a few days.

The first call was from an HR person and was very short. It included a cursory look at the interview process and appointment scheduling. I was also given an email with a great deal of study material.

The second call was a 45-minute technical interview. I received the first question about 25-30 minutes in, and then the interviewer asked me other questions about my resume. We never got to the second question.

I received a call back about a week later saying they wanted to fly me out.

The on-site involved four interviews and a lunch in the middle. The final interview had a second employee present, shadowing the interviewer.

After this, it was about a month until they got back to me with the verdict.

The final interview had a tricky question about converting a post-order tree to pre-order.
