I went through the interview process for a second time years later from the first try. They invited me for an on site interview to speak with the hiring manager. I reluctantly agreed to it. I had to spend my day off from work to drive over 6 hours to conduct a 30 minute interview that could have been accomplished virtually or by a simple phone call. Mind you the cost of gas, tolls, etc. that goes into that and is not reimbursed. I was then declined the job a day later. The process felt rushed and they seemed uninterested when I answered questions. Yes, there is also a homework assignment given before meeting with the hiring manager asking for details about how your background relates to the job. The final stage is a mock presentation to demonstrate presenting skills.

Prepare to be mentally exhausted from their interview process. Screening with recruiter, take home assignment with like 10 questions, interview with mangers, interview with VP, and a presentation. I usually do not interview with companies that have their candidates invest this much time and not worth it.
