Had a phone screening and interview. After which I was given a coding exercise (building a tic tac toe game in the terminal). After completing and submitting the exercise, which took a good amount of time, I was never replied to. After a couple follow-up emails sent, I gave up. Really unprofessional.

Long, slow, overly thorough yet arbitrary interview process. Phone Screen -> timed coding test -> panel interview with the other candidates (yes they make you interview simultaneously with the other candidates) -> pair programming.
