The whole process took about 3 weeks from the date of application to the date of offer. I initially had a phone interview, followed by 2 video interviews, and and 2 onsite interviews. The day after my second onsite interview I got the call telling me that I got the job, and I accepted the offer. What I did appreciate about MediaMath in the interview process was their transparency and how respectful they were about my time. Even though I went through several rounds of interviews, I did feel that the process was expedited and I was not left with extended periods of time where I didn't hear any updates from anyone.
