    Difficult Interview

    Application

    I applied through a staffing agency. The process took 1+ week. I interviewed at ExtraHop Networks (Seattle, WA).

    Interview

    My process involved:
    Solving a coding problem on my own and send in the code.
    Speaking briefly with a recruiter on the phone, the usual screen.
    Speaking with a developer on the phone about my code and related interests. No over-the-phone coding, thank goodness.
    On site interview: 5 rounds with about 7 or 8 people. Mostly algorithm and data structure related questions. Pretty enjoyable as far as interviews go.

    Difficult Interview

    Application

    I applied through college or university. I interviewed at ExtraHop Networks.

    Interview

    Met with them at a career fair on campus and was asked a simple coding challenge. After passing the challenge, they invited me for a technical screening interview a couple days later. After going to the interview, I worked through a single programming question for about 30 minutes. It had to do with Matrices and recursion. Heard back about a week later that I was not quite as good of a match as they were looking for.

    Difficult Interview

    Application

    I applied through college or university. The process took 4+ weeks. I interviewed at ExtraHop Networks in December 2015.

    Interview

    Applied at a College Career Fair.

    Was given a coding test to complete, which involved Downloading and reading text from the internet, processing it, then using that text.

    After completing the coding test, I was given a phone interview. The phone interview was mostly about my past projects at school and at my internships, vocabulary questions about the C programming language, and I was asked to code in a google docs.

    After the Phone Interview, I was invited to an onsite in Seattle, which started with Lunch, then a series of technical interviews.

    Average Interview

    Application

    I applied through other source. The process took 2 weeks. I interviewed at ExtraHop Networks in March 2018.

    Interview

    Had a phone chat with a recruiter and then a take home programming test. The test wasn't terribly hard, and in fact you could find other solutions for exactly their question online. I implemented my own solution that, as far as I could tell and could write tests for, was correct. I failed the test and had no chance to talk to anyone about it -- I don't know if I failed because I messed up, if they misunderstood something in my write-up, etc. Part of the problem involved manual conversion of a web page into a word list -- something that could vary between solutions. I documented how I did it, but who knows if the reviewer read that thoroughly?

    I felt it was unprofessional to ask me to spend 4+ hours of my time and then not even be willing to discuss the solution over the phone to make sure everyone was on the same page. It seems that companies are giving take home exams more frequently but not being respectful of their candidates' time.

    Interview

    Complete mess, they had me do some kind of take home test, gave zero feedback on it. Lines of communication were a mess, no one had any idea what was going on. What they don't tell you is they have a policy is NEVER allowing an applicant to apply for another job if they wash out. It's absolutely insane. You have literally one shot at this company and they will never ever consider you for another role.

    Which is made all the worse by the fact that their interview process is convoluted.

    Interview

    I spoke with the recruiter first. She then set up an interview with a sales manager and it went well and they had me talk with another of the sales managers a couple days later. I never heard back from them. I then reapplied a couple months later and they had me talk to the same person and I never heard anything back again...
