Start of the process was very quick and painless. But I didn't enjoy the interview and post interview. I would say 50% of my interviewers were pleasant and friendly. But none of them seemed passionate or excited about their work. And a few had egos--instead of interviewing me, they were trying to show off or prove they were smarter. I've ran into similar people at other companies but Audience Science had the highest concentration. As for salary, their initial offer was quite low and they wouldn't budge. But after ignoring them for a week, the recruiter voluntarily increased the base salary. Interview books describe these tactics as red flags. I also recommend staying away from companies that treat their candidates this way.
