Application Details

I applied online. The process took 2 weeksinterviewed at Microsoft.

Interview Details

Had 5 45 minute interviews back to back with 15 minute breaks in between. The interviewers talk to each other while you are taking a break before the next one comes to get you. Mix of personality/behavioral and "What would you do in this scenario..." questions. Very laid back interviewers dress is casual and you can just act like you're having a normal conversation... while also writing code on a whiteboard.

Interview Questions

    Didn't get very far. Just finished the first interview. I thought it has gone well, but apparelrntly not. Screener is very time focused, and the whole process is very streamlined. There's no question that they're looking for the best people.

    I applied through college or university – interviewed at Microsoft.

    Interview Details

    Applied both online and through contacting a college recruiter for their internships. I had an on campus 30 minute interview that they use to decide whether to bring you to Washington for 4 additional interviews. Interview questions are about as expected, and the interviewer was very polite. Overall it was a very positive experience and I'd recommend it to anyone.

    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.

    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.
    2 weeks later got contacted for final round. A couple of days later my application was changed from PM to SDET. Even though I didn't want that position, I decided to go and find out more about Microsoft.
    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.
