    Application Details

    I applied through a recruiter. The process took a weekinterviewed at Microsoft in May 2012.

    Interview Details

    Contacted by a recruiter, followed up with a phone interview. An in-person interview was then set up; the setup process for the flight was somewhat bureaucratic, but the interview itself went smoothly.

    While the technical questions were good, I found the interviewers' description of the company to be misleading and portrayed it as being far less competitive and bureaucratic and far more flexible than it actually is. If this is a concern for you I would heavily recommend discussing it with people you can trust and who have experience with other companies.

    Interview Questions
    • Questions were mainly related to my past experience, OS concepts, synchronization issues, and so forth. There was less emphasis on algorithms and more on architecture.   Answer Question
    Negotiation Details
    They made a good-faith effort to match the gross salary of my previous company. Considering Washington's income-tax laws and Microsoft's additional benefits, this worked out to be a raise in compensation. I respected this and did not negotiate.

    Software Development Engineer In Test (SDET) II Interview

    Anonymous Interview Candidate in Redmond, WA
    Anonymous Interview Candidate in Redmond, WA
    Application Details

    I applied through an employee referral. The process took 4+ weeksinterviewed at Microsoft in November 2011.

    Interview Details

    I had prior experience working as a contractor at Microsoft so I was familiar work environment. This interview was for Windows Phone Group. One of my colleague who work for MS had forwarded my resume to this opening. I was having a really nice job at one of the fortune 100 company and had solid experience with some 4 of the leading companies in the field. So my profile was good in that sense, but didnt see any mercy while doing 1:1 interviewing for the post. Initial phone interview asked about programming and testing questions. Not very difficult. Then followed by a one day interview which started at 10 am and lasted at around 5.30 pm. First one was one 1:1 hr session(just explained what I will be doing thru the day and what all i look from the job ) . Five 1:1 technical sessions , Initial ones where easy , but as soon as they realize that you are able to answer the initial rounds, the other ones will go tougher and tougher till you break.
    So you really dont have much idea of how you are doing, but it seems after four rounds you could be relatively safe since the questions are hard to crack questions by then and they also know about that. There is a lunch break that too filled with some technical and some personal talks. By evening you will get exhausted, so keep your energy levels really up till the end. They will give you indications about the result. The last person I met was a higher level manager and he told me ,that they liked me and that I had done well and HR will get back to you. After two days I got the offer. Dont go without enough preparation, for sure its difficult to crack without proper study , prepare well , at least it will give a nice experience . Good thing is even if you don't get its a nice experience.

    Software Development Engineer In Test (SDET) II Interview

    Anonymous Interview Candidate in Bellevue, WA
    Anonymous Interview Candidate in Bellevue, WA
    Application Details

    I applied through an employee referral. The process took 1+ weekinterviewed at Microsoft in November 2011.

    Interview Details

    I've been through this process with Amazon and Google before and the phone screening process is pretty much the same. Not too many questions about resume or experience but algo and data structure questions.
    Got a response the next day to tell me they wanted to bring me in for 1:1 interviews. Trip was schedule for the following week and the process is made very easy by the recruiter. They take care of everything for you and you just have to approve the final travel arrangements.

    My on-site interviews started with a 30 minutes meeting with my recruiter. He then brought me back to the lobby area where the first interviewer (an SDET II) came to get me. We went to his office. We went through a couple of algo and data structure problems and he then asked me questions about design patterns and other behavioral stuff. It was about 60 minutes including some time for me to ask questions.
    The next interview was over lunch (also with an SDET II) but was very similar. Being during lunch, the discussion seems a little more casual but you are still being interviewed and you still have to solve problems.

    The last interview was with a Senior SDET Lead, in his office. He gave me an algo problem and a UI design question. The rest was based on my past experience and some behavioral questions. We ended up spending more time talking than solving problems.

    I was pretty confident after the first 2 interviews but it all went downhill during the 3rd one. The reaction and facial expressions of my interviewer made me feel like I was getting it all wrong. He told me at the end that I was done which confirmed my feeling was right since they usually schedule more interviews if you are doing well.

    Interview Details

    All questions were technical. I had 3 coding questions and several test questions probing on what I had done. Coding questions included reversing a linked list, inserting into a binary search tree and deleting a node from a binary tree. I was asked to come up with test cases for my code. In addition I was asked to come up with a strategy and test cases for an internet voice calling software product and a toy for a toddler. Overall the interview experience was very positive and interesting.
