The interview process lasted about a month long. It first started with a phone screen with HR with questions about why I was interested in the job and a couple of technical questions. After the phone interview I was invited to an in-person interview where I interviewed one on one with 4 different people. This interview had a couple more technical questions and included answering two coding questions. The third and final interview was again in-person with 3 different one on one interviews, but did not have any technical questions.

I submitted an application through indeed.com. Mercury Systems HR responded with a request for interview 4 days later. I had two interview, one was a video conference for an hour the second was an onsite interview also for one hour. The time between each interview was about a week. The time taken to notify me about the results was also a week.
