AppNexus interview questions

HR reached out via Linkedin to schedule a quick phone screen. A second phone screen was subsequently scheduled. After that, I was asked to come in for a potential full day of interviews. This was great, except for the fact that a specific date and time was sent through without asking for availabilities. Luckily I was able to make this work, but requiring a full day off for an initial interview was pretty aggressive. The day's schedule was to have two separate hour-long interviews in the morning, a lunch, and then a decision point for AppNexus. They would let you know if you were going to be brought back for the afternoon session of more interviews. When I arrived in the morning, I was surprised to find three other candidates also there for interviews. We were given a group tour of the office, and then separated into our own conference rooms. We were told it wasn't a "Hunger Games style interview", but in reality, it was. This seemed like a setup for an entry-level position, rather than a position targeting someone with 8+ years of professional experience. The first of the two interviews was a normal conversational interview. The second one was more focused on knowledge and those annoying logic brain teaser questions made famous by Google. I guess they missed the memo where Google no longer utilizes these types of questions in their interview process. Overall, it was clear that each interviewer had a specific agenda for the interviews with specific criteria for evaluating the candidate. We were given sandwiches from Pret for lunch, and then they came in with the decision. Ultimately I was not asked back, but I know someone who was on another interview and it was more of the same. All in all I thought that the interview process was a bit demeaning for someone coming in with almost 10 years of experience, especially given that they had reached out initially. I understand this may come off as bitter, but being expected to take a full day off for this interview process, which ultimately wasn't even needed, was a waste of time. Also, being given a specific day without asking if I was available was a little strange.
