    Software QA Engineer Interview

    Anonymous Interview Candidate in Mountain View, CA

    Positive Experience
    Average Interview

    Application

    I applied online. The process took 2+ weeks. I interviewed at 23andMe (Mountain View, CA) in December 2016.

    Interview

    23andMe interviewing process really stands out of other hi-tech companies in Silicon Valley. First, they start from a phone chat with the hiring manager. Most other companies will use their HR people to talk with candidates. Second, they give you up to 2 days for a coding test t be done at home. Most other companies hit you with 1-hour "supervised" test, which is not working for me and,I assume, for some others too: I am getting quite nervous and the help, which is provided, usually only disrupts my train of thought. Third, and most importantly, on my request the HR lady did provide me with the feedback on my coding test after I failed it. I usually ask for this kind of feedback, but got only radio silence in return from about a dozen of other companies.

    There were about 10 business days from my initial application to the reply from HR offering to set up a phone call with the hiring manager. The code test was available the day after the call. It took them about a week to let me know that they were "moving ahead with another candidate." It took them 4 days to provide the feedback I asked about.

    Interview Questions

    • While talking with the hiring manager, I was asked about my work experience, my knowledge of 23andMe, and some basic questions to gauge if I know Python, Selenium, and general testing methodology.

      The code test was to write a Selenium-based automation (preferably in Python) for testing an online store.   1 Answer

    Difficult Interview

    Application

    I applied online. I interviewed at 23andMe (Mountain View, CA) in September 2017.

    Interview

    It starts with a phone call with the HM to talk about background, interest in the company and projects. Then there is a coding phone screen, and other design questions to gauge one's analytical skills. If you manage to do well on the previous two interviews, they bring you onsite to meet the team. They are looking for strong coding, analytical and social/culture fit at the same time. Also one of my interviewers pointed out that brute-force solution is perfect as per their requirement.

    I enjoyed meeting and working out solutions during the onsite interview. Everyone I met was very amiable and grounded. The most annoying part is communicating the interview outcome with a standard email without any particular feedback! Really, there is no way to call, and talk to the recruiter.

    Senior Web Developer Interview

    Neutral Experience
    Average Interview

    Application

    I applied online. I interviewed at 23andMe (Palo Alto, CA) in July 2017.

    Interview

    Interview process was smooth, no issues there. 3 ppl interviewed me. It was a great interview. I answered all their questions. One interviewer even mentioned that I was able to answer a question that no other candidate has answered. The hiring manager even mentioned that the next step would be another round of management interview. Then suddenly after a few days I get an email that they went ahead with another candidate. I dont want to believe what other reviewers mentioned about 23andMe hiring people more for their compatibility with the young crowd that works there, but it does make me wonder. But overall I had a very positive interview experience. I believe in what they are bringing to the people, and I wish them all the best!

    Average Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at 23andMe (Mountain View, CA) in February 2017.

    Interview

    Applied online. Got a request for a phone interview within a couple days. After the phone interview, I was asked to come in for a 3 hour onsite interview with 4 developers. They all only asked syntax questions and had assignments for me to complete. E.g. how to code an auto-complete feature in JS, how to create a circle with a double border in CSS only, how to write a traffic-light control code, how to code a simple html form. At the end of the interview, however, I learned that the position for which they were interviewing me has already been filled last year and they don't really have a need for another developer. They just left it open in case they find someone extraordinary. I think it may be their standard practice, since I now see a lot of people who interview with them don't get an offer in the end.
