You will first receive a writing assignment they send over email. You have one week to finish, the task is fairly simple (only looking at Excel and write conclusion.) next you will have a 30-min phone interview. But the person you talk to is only HR that does not involve in their daily work. The last round will be a 3-hour interview (logic test then meet 3 team leads) that asks the same questions, they are on different teams, that's why. The overall process took 3 months, hence if you old an OPT, the 90-day unemployment will expire soon if you plan to wait for their slow reply.

The interview process is incredibly long. After the initial application they send you a writing test where you do some basic data analysis and write a short memo. This is followed by a phone interview, and finally, three back to back to back interviews with different members of the team after a timed statistics test. My interviewers changed last minute and it was reflected, as the first group seemed disinterested and asked questions more suited to the statistical programmer, rather than writer/coordinator role. It was a long wait for a response as others have noted, almost 2 months after to receive a no. Recruiting was very nice and helpful throughout the process, but that is a simply ridiculous amount of time to wait, especially when similar firms move much quicker. It was especially discouraging after the amount of work they have you put in throughout the process. Would have categorized it as positive until the final round + wait, which really left a sour taste in my mouth.
