Software Development Engineer In Test (SDET) Interview

Anonymous Interview Candidate in Sydney

Interview Details

An hour long phone interview first with basic problem solving questions (not much coding). And an on site interview at the Sydeny office (for a position in US). 4 interviews, all very technical. Did poorly in the first two. Very good in the third. The fourth interviewer had to make the call, in which I did decent. Whole process took around 3 months.

Interview Questions
  • I was asked to think of ways to reduce memory usage / make it more efficient for the Windows Help files. This was asked in my second interview. I tried to think of suggestions but none seemed to click with what the interviewer had in mind.   Answer Question

    First round is phone interview calling from US, lasing for 40 minutes. Second round is the final round. I was heading to their Sydney office. There were 3~4 rounds interviews. Every round is 45 minutes, comprising a programming question. You have to be very careful about the details of each step of your code, especially the boundary case. Questions are all moderate difficulty.

    Three rounds of interviews, each with a pair of interviewers, one will focus on tech skills and one on soft skills. Each pair usually comes from a different team, and between rounds will advise each other on questions that were strong or weak from the candidate.
    If successful there is a fourth round of interviews with the local lead in the discipline for which you're applying (SDE or SDET.) If very unsuccessful, there won't even be three.

    I was contacted by a campus recruiter to do an on campus interview. The interview was very non-technical and afterwards I was invited to interview on-site for an SDET position. They flew me out and paid for food and housing, then I spent a day interviewing. The interviews themselves were fine, not terribly difficult, but I wasn't set out to be a SDET so I didn't prepare and showed that in the testing specific interviews.

    Interview Questions
    • Lots of "is this ready to ship to the world" questions, can't remember specifics.   Answer Question

    Interview Details

    It was a phone interview. The interviewer rushed me through a 30 minute interview asking a combination of technical and behavioral questions such as how to build a queue from two stacks, Boxing, encapsulation, how to build a battleships game. He also asked what the most complex question I have had to solve is and how I tackled it. I hardly had time to ask any questions at the end.

    Interview Details

    Had 5 45 minute interviews back to back with 15 minute breaks in between. The interviewers talk to each other while you are taking a break before the next one comes to get you. Mix of personality/behavioral and "What would you do in this scenario..." questions. Very laid back interviewers dress is casual and you can just act like you're having a normal conversation... while also writing code on a whiteboard.

    Interview Questions
    • Question about Data encryption over HTTPS websites and he drilled really deep asking questions like how secret and private keys work, how the secret key is shared, and how encryption of data actually takes place on websites.   View Answer
