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

    1 round is phone interview, asking your past experience, basics in C/C++, the difference between C++ and Java, and how to identify a heavier ball in 12 ball in 3 times. 2nd round is a on-site interview. you will meet with 3~4 interviewers during the day, first one asked me how to calculate the sum of a binary tree at certain level, second asked me to write how to check if a string is a palindrome. 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

    Interview Details

    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.

    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

    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.

    Initial screening was done by an external company. They were polite but seemed to follow a script. They possibly did not understand the technical questions. In the end, I am not sure if the answer given was wrong or just did not meet their scripted answer.
