First thing first: DO NOT APPLY THIS COMPANY! It is a total waste of time taking interviews there. They do not have a mature and stable process because they have different process every year and mine is very redundant. I never heard that it needs 5-round interviews for an intern. They just let you pass all the interviews and play you around waiting until they find someone better, then just dump you like trash WITHOUT ANY REASON. So unprofessional and lack of responsibility.

I interviewed for the ThousandEyes summer internship position February 2019. The process was extremely quick and accommodating. When I was first contacted by the recruiter, I mentioned that I had an offer with a deadline at the end of the week and expressed my doubts to whether I could complete the interview process in time. The recruiter scheduled an interview for the next day, and after that, a final interview with the senior engineering manager and a lead software engineer. The offer letter came in 3 days after I was contacted by the recruiter. Overall, good experience that was a quarter of the duration of interviews with other companies.
