Snapshot Interactive Associate Project Manager interview questions

After submitting my resume and cover letter through Indeed, I received an email from the Director of Office Operations inviting me to a group interview. This struck me as odd, as I've never had a group interview for anything other than a part-time retail job, but I agreed to come to one of the two time slots she offered. At the interview, there were four interviewers (the head of the company, the GM, the office manager, and a PM) and five or six other candidates. The head of the company asked very standard interview questions, and we went around in a circle and answered them. The best word to describe this process would be tedious. The head guy explained that they do these group interviews because it saves them the time of having to interview all the qualified candidates individually. With this setup, however, each candidate only had around 7 minutes total talking time, and there was no opportunity for conversation. I'm not sure why they couldn't just do a 15-minute phone screening with the qualified candidates and then invite the ones they liked in for an interview. They may have saved time on their end, but for the candidates, this process is a huge time-suck, and there's no opportunity to actually engage. I spent an hour listening to other candidates talk about their experience and learned almost nothing about the company. The little I did learn about the company seems to match some of the negative reviews here on Glassdoor. They emphasized their ability to get projects cranked out at lightning speed, and the GM boasted that the PM present typically handles between 60 and 80 active projects at a time. Having worked in and with agencies in the past, I don't know how that's possible without sacrificing quality and/or totally overworking your employees. Their philosophy seems to be to get as much done as quick as possible, and that even extends to interviews. I thought the interview went well enough for what it was, but since we had so little time to speak, I left having no idea which of us they would invite back for a second interview. Within a couple of hours, I received an email saying that I was not the right fit for the position, and after this experience and reading the reviews here, I can't help but feel that I dodged a bullet!
