Had 5 on-site interviews and lunch with employee. In ~2 weeks got a call from recruiter that I have an approval from hiring committee but there are no open positions. It is been more then a year since, couple of recruiters changed during that time and finally my hiring committee approval has expired :( So even though I passed interviews I never got an offer.

Very professional process. Every person I interviewed with was very professional. You are give all the information you need to go through this process. It can seem intimidating at first. There are multiple interviews. They explain to you the subject matter of the interviews. They provide material from which you can study. They even personally reach out to you if you do not get the position. Most companies just send an email or ghost you. I would recommend this company to a friend.
