Interview
First I had a phone interview followed by a 2-hour in-person interview with multiple members of their team. I ended up not getting the position but they let me know by sending me an automated email about "...after reviewing your resume, we have decided not to proceed." This is not something you send to someone after a 2 hour in-person interview. I emailed them asking if this was sent by mistake and if not, what could I have done differently. They did not respond.

Two phone screenings, One from Recruiter and One from Manager and Then a 4 person in person interview. Very important you're a great culture fit for the company. If you are, you will definitely get the job.
