The interview process is what one would expect to experience from any tech company: Resume Review, Phone Screen, Take home assignment, and 6-8 hour onsite interview.
I was initially contacted by the management team to do a Phone Screen. During the Phone Screen, I was impressed with the way the interviewer helped me to understand the process. I stumbled on the questions asked here. However, the interviewer gave me an additional assignment to complete which involved understanding how traceroute works at the lowest level. At the end of the Phone Screen, I was given topics to review and invited to set up a free trial with the ThousandEyes Product. After a few days, I was informed by the company that I was moving forward in the interview process.
This is where the interview process became challenging. I received a take-home assignment which involved several different troubleshooting, networking, communication, and process-thinking based questions. I would be remiss if I did not mention the level of difficulty of these questions. They are clearly designed to be challenging and make one think. I was not disappointed. You have one week to complete this assignment, but additional time will be given if you request it. It took me 6 days to get through these questions as I had to do quite a bit of research. I believe this is by design. About a week later, I was notified that the company was moving forward in the interview process.
The next step was to go to an onsite interview. I interviewed with three other Customer Success Engineers, the Director, and had a panel interview. The three Customer Success Engineers asked me technical questions relating to how the internet works, Linux sysadmin, and general customer interactions. The Director asked me "cultural fit" questions. Then came the panel interview/challenge.
You are given one hour to prep for the challenge. In this hour, knowledge of the ThousandEyes product is key, which is why one is invited to set up a free trial so early in the interview process. I highly recommend one does so. After this hour, you are in a conference room with four or so Customer Success Engineers. I cannot stress enough how attention to detail and well-thought-out statements are important to this portion of the interview.
At the end of the day of interviews, I was mentally exhausted. I felt challenged and motivated. A few days later, I was notified that the company wished to extend an offer, which I accepted.
