Had a 1st round interview for 1 hour with simple coding questions. A week later heard back for next round for 3 hours. Had to create a UI+database design for an app and a 1.5 hour role playing which felt very much like a customer support job interview. I though this was the final round since the interview process was longer than other companies. I get an invite for another 3 hour long round with 3 interviews. Had brain teaser type problems that test my logic and 2 more behavioral rounds. I was able to connect well with my interviewers except the last one who didn't have my resume and seemed to be totally disinterested in what I was saying. Got a rejection 1 week later. Honestly, I wish they let me know sooner since spending 7 hours interviewing and not get any feedback on what I could improve on felt very discouraging.
