My experience with Mathematica's interview process lasted three months. I applied online at the end of February. I was contacted a month later for a screening call by a senior talent acquisition coordinator. The coordinator sent me several dates, to which I replied within an hour, and then emailed me a week later with a new date. The screening call was a 30 minute phone interview with a Human Services Researcher. We had a lovely call. The interviewer assured me that it would be a long process, but I was welcome to follow up with her or the HR coordinator. She said "there's no wrong door." Following our conversation, I sent a thank you. Two weeks after the screening interview, I hadn't heard any updates so I emailed the coordinator to follow up. Two weeks after trying to contact the coordinator, I emailed the interviewer to follow up. I never heard from either. I checked the careers.peopleclick.com account for my application status regularly, and it was through the account that I saw my application status switched from "considering" to "not selected". Had I been selected to move forward in the process, the next and last step would have been a half day of virtual interviews. There would have been about 6 half-hour interviews with two interviewers in each session, each session focused on a different skill set. The screening interview itself was a lovely conversation, but I am disappointed in how the communications were handled - both before and after the interview. I know that hiring is a taxing and consuming process, but I would like to see Mathematica (as well as other employers) treat applicants with more respect for applicants.
