Mountain View, CA (US)

I applied through an employee referral and the process took 1 week - interviewed 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 Question – 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 through college or university and the process took 8 weeks - interviewed at Microsoft in January 2013.

Interview Details Felt highly disorganized. Issues with email/reminder system and several communication problems with pre-interview process. Might have been something like a bad email responsible, but either way, the experience was not good, and resulted in stressors such as "are you coming to the interview next week?" (I had no idea...), and an unfortunate surprise that I was being interviewed for SDET, not SDE, which was something I had explicitly not indicated an interest in.

There were 4 interviews. Was late to one of them thanks to the whole process starting late starting with interviewer #1... could tell this made a negative impression, but there was nothing to be done.

One interviewer really did not appreciate being asked about stack rank and took it as a sign of fear /poor work ethic, although others were more receptive.

Overall, not impressed and felt like they wasted my time, but the feeling was apparently mutual. They were very good about reimbursements and accommodations though, but I wouldn't consider interviewing there again.

Interview Question – There was some sorting thing using an array. It's been a bit too long so I don't really remember. Also some test-related questions for which I was unprepared.   Answer Question

I applied online and 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!

Interview Details 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.

Software Development Engineer In Test (SDET)
Bellevue, WA (US)

I applied through college or university and the process took a day - interviewed at Microsoft in October 2012.

Interview Details I was being interviewed for a summer internship with this title, they flew me up to Washington for an in-person group interview after a screening interview at my college (which I got through handing a resume to a recruiter through the career fair). This screening interview was fairly simple, one technical question, some questions about what I'd like to work on, etc. Everything is paid for when you're up their, car, hotel, and food.

In person interview was a 5 rounds that either lasted throughout the morning or afternoon (there were two groups of interviewees from colleges across the country) and you spend about an hour with each person, and by the end they tell you on the spot if you've passed or failed.

Each interview asks some type of technical question where you solve an algorithm, everyone asks for a self evaluation on how you think you're doing at this stage in the interview.

Office where I interviewed was fairly interesting, one section had meeting rooms that all referenced video games from Halo to Half Life, there was also one of those Microsoft tablet tables with games on it, as well as an Xbox 360 running Halo. They serve some food, but it's not worth remembering, and there's breaks in-between interviews where they very much discourage you from discussing any of the questions being asked.

Interview Question – Nothing too difficult about the technical questions, I came from a public school in CA near the start of my JR year, and by the end of the year every type of question that was asked was covered in class. They don't look for the absolute best answer, as long as it's not overly complicated.   Answer Question
