Software Development Engineer In Test (SDET) Interview

Anonymous Interview Candidate
Anonymous Interview Candidate
Application Details

I applied through a staffing agency. The process took 3+ monthsinterviewed at Microsoft.

Interview Details

Got contacted by an outside recruiter for a phone screening. Then they offered to fly to an external hiring event. Had standard 4 (or 5) technical interviews + one behavioral with the hiring manager. Got an offer a couple of weeks after that. Relocation and other parts of the transition went smoothly, the team(s) responsible for that know perfectly what they are doing.

Interview Questions
  • Can't remember the actual questions now, but those were usual interview ones. No crazy trees or graphs, but mostly combinatorics-like, string/array manipulation, basic geometrical applications etc. No brain teasers, only technical.   Answer Question

    I applied through a recruiter. The process took 7+ weeksinterviewed at Microsoft.

    Interview Details

    It started out with me reaching out to a recruiter through Linkedin. I was then told if a hiring manager is interested in my resume, I would be contacted shortly. I heard back next week and was then set up for a Skype Interview. This interview lasted for a hour and questions were pretty straightforward (One coding question and one testing/design related question).

    In the next week after the Skype interview, I was contacted once again and invited onsite for 4 interviews.
    Interview 1: Lunch interview which included knowing more about the team and what they are working on. After the lunch, we went back to the office and there was whiteboard coding questions. This round lasted for about 90 minutes.
    Interview 2: The interview started with me describing (Sequence Diagram) of my current project. After that I was asked a coding problem and was asked to determine the test cases. This interview lasted for about 60 minutes.
    Interview 3: A purely testing question followed by some whiteboard coding. This interview too lasted for about 60 minutes. After this interview, the interview told me that my next round of interview would be with the Hiring Manager.
    Interview 4: Purely behavioral and the hiring manager sees if you are a good fit for the team.

    Heard back in a week and was extended an offer.

    Tips: Don't be scared. I was a little overwhelmed when I walked through the campus but then the HR along with other interviewers really ease you into the interview. Talk loudly as the interviewer then knows what you are thinking about. I was given few hints when I was stuck and the hints really help in that case. Also I was really comfortable writing code on the whiteboard as I spent 2 weeks before the onsite interview practicing on the whiteboard. This really helps. A must do!

    Approach the testing questions in a very structured manner as they really like that. Cracking the coding interview has those steps mentioned.

    Resources: Geeksforgeeks - This is the only online resource that I referred as I had gone through Cracking the coding interview and Programming interviews exposed in the past.

    Interview Questions
    • Nothing that difficult. Just know your basics about data Structures, Algorithms and Testing if interviewing for a SDET position.   Answer Question
    Negotiation Details
    I negotiated a bit as I did not have any other offers. But please negotiate as there is always room for more.

    Interview Details

    This was a very standard interview process where I received a phone screen by HR, then a phone screen by an engineer, and then finally I was flown out to the location for around four interviews lasting an hour each. There was no lunch break as the interviews were from 1-5pm

    I applied through an employee referral. The process took a weekinterviewed at Microsoft.

    Interview Details

    Very fast process for me, but have heard that it went slow for some others. So varies.
    Got a phone screen with some technical questions, then an onsite within a few days, and an offer a few days after that.
    The interviews were good, lots of whiteboard coding questions but good questions, nothing stupid. Some basic sanity checks, i.e. very simple questions, some slightly more complicated (e.g. rearranging linked lists). Long day.
    If one or two interviewers give a solid thumbs down they often stop the process so they do not waste time, so if the interview is shorter than expected then expect bad news. If you make it to see the hiring manager it is a good sign.

    Interview Questions
    • Honestly don't remember, but I was not stuck anywhere so there was nothing too ridiculous. But they do expect you to think of edge cases and test cases, especially for an SDET.   Answer Question
    Negotiation Details
    I did not negotiate but should have. I asked for too little and got it. Research the market and ask for slightly more than you want.

    I applied online – interviewed at Microsoft.

    Interview Details

    After my graduation, I posted my Resume at Microsoft's global career website, HR contacted and scheduled phone screen that was an hour long, I was invited for onsite interview full loop, the onsite loop involved first some information exchange with HR person, then I was approached by would be manager, he welcomed at the reception and sent over to another member on the team to be interviewed, I had 3 interviews back to back and one of them has been a lunch interview, then I met the would be manager (a test lead) again for the fourth interview, all first four interviews were whiteboard sessions, and we also chatted on my resume, past experience, general questions like where do see yourself in five years from now, etc etc. All the programming questions were on data structures and algorithms and core CS concepts. My fifth interview was with hiring manager (a Test manager), he also sent me to board for another whiteboard session, then asked me various test questions, like give test cases for testing the keyboard, coffee mug, MS Paint, then he started over resume and asked me questions on my research assistantship experience and projects that I completed there. All the interviewers were very respectful, between each interview they asked me if I cared for a drink. It ended up very happy and memorable experience, I was offered the job!

    The questions were basic, but then you make these simple programs and add robustness to them. i thought that it would be better to go with the easy stuff and it actually turned out to all be hard so there is really no way around it. But it is microsoft, so that makes sense
