Software Development Engineer In Test (SDET) Interview

Anonymous Interview Candidate in Sydney
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

Third one is to about the Tic-Tak-Toe game, write a function to check if someone has won at the current board situation.

    Interview Questions
    • The third question is a bit unexpected. I was spending a lot of time thinking how to write this efficiently, but didn't finish it. I should just write a straight forward one, and try to improve it later.   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.

    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.

    Hiring through career fair at top-tier school. Skype interview first and then on-site at Redmond. Skype interview was for PM position and was pretty straight forward.

    Final rounds was 3 interviews (1 SDE, 1 SDET, 1 PM) and lunch. A fair amount of coding and a full behavioral with the PM.

    Microsoft came to our school to interview students.
    I had applied for test engineer position.
    They had catered a huge sandwich which I thought was nice.
    I was interviewed by one of the two Microsoft engineers.
    They dressed casually and told students to dress casually for the interview.
    Yet many students came in full suits.
    Interview last for about 30 minutes.
    It wasn't an onsite-interview

    Interview Questions
    • They asked to write code for reversing a string.
      And then they would ask you how would you test the code.

    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.
