Commonwealth Fusion Systems interview questions

Multiple interview rounds, made it to second round. Last interview is a 8 hr in person interview. Recruiter was very nice in phone screen but didn’t have a good “vibe” with second manager interview and didn’t proceed.

Phone call with the recruiter. She basically described what the company does, which I already knew. She asked me for my background, I asked a few questions. Didn't last longer than 15 mins. The next day I get an email they are going forward with other candidates. I mean at that point they dont even know me lol. They've seen my resume and they agreed to interview me but declined after recruiters call?! They are a startup and they haven't make any revenue yet. (First red flag). They do not have an office for IT (second). Recuiter started to laugh so hard when I asked if IT have an office(also cringe). She said you are going to sit so close with 3-4 other people. You are going to be exposed to strong magnetic and for that reason u can do any MRI.(third red flag). Just avoid this startup. Svae yourself some time.
