I first got a phone call from HR screen interview. Then I Talk with recruiting manager. Onsite: 1 round of presentation, 3 rounds of machine learning research design, 1 round of coding questions, lunch is to talk with a manager.

Talk with the manager on the phone. They want me to visit onsite for the first interview. I went there speak with the hiring manager and a data scientist, total of 2 hours. Then I had a full day interview from 9 am to 5 pm. I believe the hiring manager was not super interested in his job. He was kind of lost for how to conduct the process. They have no respect for interviewers time. I wasted a total of 2 PTO days, plus time for presentation preparation. Overall I am not impressed with their engineers. The energy is very low for a startup. Most importantly they do not have a plan for future developments. I had an interview for this job for 4-5 months ago. I see they still did not hire anyone. I believe the purpose of the opening is getting ideas from researchers and implementing by their self.
