Integral Ad Science interview questions

Initial phone screen was with recruiter who asked basic questions: background, salary expectations, etc. 2nd round was in person with direct manager and director. Direct manager seemed like a very nice guy, I liked his personality a lot and think our personalities would get along well. Both stressed long hours and were upfront about expectations that this role is much more than 40hr/week. It's nice that they are upfront so you know what to expect. 3rd round- video phone call with a senior manager and VP. VP was very nice, I liked her a lot. This was just a culture fit screen, so nothing too difficult here. After my last round, one of the managers emailed me asking if I would relocate and "pay for it myself" to another state even tho the job listing was for SF. A few days later, I received an offer but it was below the salary expectations the recruiter and I talked about. To be honest, after interviewing with them team, my salary expectations were much higher to accept the position. But what they offered was not even close to my current salary or competitive for the position. The recruiter wasted my time-- the salary was 20% below market & much lower than my expectations from the initial phone screen.

I was contacted by a company representative directly over LinkedIn back in March for this role, after we exchanged correspondence and I sent them my CV they had invited me to have a telephone screening with HR. I have booked the telephone screening however they had forgotten about it and I had to reschedule it for the next day. During the screening it felt more like an interview, and I got the general impression from the get go I was not a right fit for this role as my experience is quite different. Left the telephone call feeling unsure - HR had said hey would check with the hiring manager if they would even consider me for an in person interview! At this point I was ready to throw in the towel, despite the fact they had come back a few days later to say they would like to invite me to their onsite offices in London. Feeling uncertain I decided to go anyway, met the hiring manager and the interview felt really relaxed (when I showed up at around 5 everyone was on the drinks) so this could be a nice place to work at. After feeling like the interview was a success I had reached out to the company for some feedback- which I never received after multiple emails asking them politely for. I guess at this point I realised I never actually got the role however I think it's very unprofessional to not give a candidate any sort of feedback whatsoever. Especially if you invited them for an in person interview in your officers And the fact they directly contacted me over LinkedIn for this opportunity- you would think there would be some more personal investment in me, but I guess not!
