It was long, drawn out, and difficult. It spanned over several days, and there were a total of five interviews. Each interview was rather draining and stressful. I understand why, but I do not enjoy this style.

It wasn't easy, nor was it hard. I already had a job, so it was more of an internal promotion rather than a true interview. It was very laid-back overall. I would recommend interviewing yourself, as it is most rewarding.

First, an email, then a phone call, then a second phone call. Next, an initial interview. After that, I met with more people on a different day. For the next interview, I had to show my basic skills with writing code.
