I talked to a recruiter at a college career fair for a good 20-30 minutes, and I was contacted for an interview. First interview went well - the interviewer was friendly and very enthusiastic about his work. The questions were mainly questions to test how you think and how well you explain how you think. There were a few simple basic algebra questions but they weren't very hard. The interviewer was also very informative when answering any questions I had. I got a call from a different recruiter the next day saying they wanted to move me ahead, and I was scheduled for a 24 hour challenge by the end of the week. The challenge had two parts - one writing a spec, and the other doing some analysis on Excel. At the beginning of the 24 hours, I got to talk to one of their analysts to ask any questions I had about the challenge. Since the challenge is worded vaguely, I asked a lot of clarifying questions, which proved to be helpful for when I worked on the challenged. It seemed like they wanted to test if you knew which questions to ask. There was a lot of data that they wanted analyzed. There was no straight-forward way to complete it, so you have to be creative in how you approach it. About a week after I submitted the 24 hour challenge, I got an email asking to schedule a final on-site interview. Since I was going on a trip for a while during the time they wanted to interview me, they let me do the interview after I got back, which was nice. I interviewed with three people - 2 senior analysts and one HR/Culture representative. I had an hour each with each interviewer, during which they asked me questions about my past work experiences, why I wanted the job, etc. I was also asked a few technical questions - 2 math problems and one JavaScript problem. The Culture representative asked me about hardships I had overcome in my life and what type of person I am. The interviews seemed a little redundant, since the two analysts seemed to be asking similar questions to each other, although the Culture representative asked completely different questions. One of the interviewers in the final round seemed to write me off for the job because of my major and background (which she knew from my resume), which really should have been done before or during the first interview, not the last one. She spent the entire hour trying to convince me that I didn't want the job. She also repeatedly interrupted me while I was answering her questions and wouldn't let me finish my answers. Coupled with the fact that she kept rolling her eyes at my answers and even sighing during the interview, I thought she handled the interview very unprofessionally. She made it seem like I was wasting her time by doing this interview. If she didn't want me from just looking at my resume, I don't think they should have asked me to come in. Besides the one rude interviewer, I had a positive experience with the rest of the process. The one bad interviewer tainted what would have been a generally positive experience, especially since she was one of the last Medallia people I had interacted with, which is unfortunate. I do think their organization could have been better though. I had four or five different recruiters contacting me throughout the process, and two different recruiters tried to schedule the same interview with me. The recruiters were very friendly and helpful, but it kind of just seemed like they were confused as to what was going on themselves.
