First was a standard phone screen: HR conducted screen on her personal cell phone, which had horrible sound quality so I couldn't hear much of her rushed mumbling. She was nice though. Next was an in-person interview: Took an hour-long math test based on story problems and hypothetical situations (moderate difficulty, but time management is the main factor!). Then had several back-to-back half-hour long interviews with senior analysts and VPs. I agree with another reviewer in that they kind of do the "good-cop bad-cop" thing. My first interview was so chill. Pretty much just a low-key conversation and was literally told I had perfect answers and that he hoped I'd get hired. Next one was late, laughed at my answers (which were essentially the same as the first one), and had his phone go off 2 times in that half-hour. VP also laughed. Extremely immature. The final one was also fairly chill. The nicest and most professional ones were young (around my age). You'd think that senior staff would have more professionalism. Afterward, we had basically a Q&A where all candidates just asked basic questions about the company and the roles. One didn't even seem to like her job that much. The overall in-person interview lasted ~4.5 hours. This was a mostly okay process, but the biggest complaint I had was the immaturity of senior staff. Not sure whether it's intentional or not. What I did and the advice I'd give to everyone: 1) Obviously, ignore their lack of professionalism. Try to seem completely unphased. They might actually be extremely rude or perhaps it's a tactic to see how you handle difficult people. 2) Brush up on your basic math skills: Percentages, data interpretation of tables and charts, and other related basic research level skills. (HUGE hint: Practice making and organizing tables and charts based on hypothetical data.) You ARE given a standard calculator, 3) Be yourself. Don't try to be the "I'm a perfect employee, I'm the hardest worker I know, and I'll do absolutely anything to be here!" type. 4) If offered the role, REALLY consider whether moving to an extremely expensive city is work the low pay. Consider finding yourself a roommate in the outskirt areas of the city. Traffic to and from work will suck, but you will not be able to afford a decent living situation by yourself. Was not offered a position. I had an extensive research background, but the other candidate had actual marketing experience. Not the worst interview process, but it could use more communication. (One of my interviewers apparently "forgot")
