Software Development Engineer In Test (SDET) Intern Interview

Anonymous Interview Candidate
Redmond, WA (US)

I applied through an employee referral and the process took 4+ weeks - interviewed at Microsoft in November 2013.

Interview Details Interview process was very pleasant. I had a single phone interview (problem solving in nature) and was then flown out to Redmond a month or so later. Microsoft gives you plenty of resources to do the things you want while you're out there, so take advantage of it. They'll pay for cab fares, but I recommend getting a rental, to make sure that you're on time to wherever you need to be. On the interview day, I was shuttled to HQ with a group of other candidates (about 15 others). We had lunch and learned about the interview process. There were a total of 4 45 minute interviews, each with a different person. Each interview was pretty similar: about 15 minutes getting to know you and about 30 minutes of coding/problem solving. The questions weren't too bad...make sure your answers are geared towards a testing standpoint.

Interview Question – A question that I was not ready for was a networking question: about how traceroute works. The interviewer gave hints. It had to do with the TTL of a packet.   Answer Question

I applied online and interviewed at Microsoft.

Interview Details I submitted my resume online through the Micro website. Several months later I received an email for a phone interview. The interview was about half an hour and we mostly discussed previous projects of mine-- there were a few questions to pick my brain and hear thought processes. The interviewer of course asked about prior experience as well.

Interview Question – The questions I was asked are previously posed on this thread.   Answer Question

Software Development Engineer In Test (SDET) Intern Interview

I applied through college or university and interviewed at Microsoft.

Interview Details I had an on-campus screen and didn't feel that I performed very well, especially with the behavioral questions. Nevertheless, I got an email inviting me to interview in Redmond, WA. The day of the interview, I was nervous, but excited and enthused. My optimism and cheer carried me throughout the day. Everyone I met was so nice and genuine, and declined all phone calls and texts to give me their full attention. One of my interviewers gave me a hard time for not understanding his instructions for testing an algorithm I wrote, but I kept a smile on my face, took his criticism, and ended up giving my own good insight on the solution. I solved every problem during the day, although I didn't always get the best solution the first time. I was very thorough in my testing of each algorithm.

I was very excited to find out that I would be getting a 4th interview, which was with a manager. The function I had to code during this 4th interview was fairly straightforward. It was also easy to test.

Regarding the culture, as I said, everyone was very genuine and attentive. These were all people I would be excited to work with, and I had some pretty good banter with most of them. I got the affirmative interview results soon after. I had a great time in Seattle, and Microsoft of course paid all the expenses.

Interview Question – I would rather not disclose any interview questions. I will say that half the questions I got were very personalized, while the other half are similar to the ones you can find online... Know your algorithms, data structures, and design patterns. My networks, information security, databases, compilers, and finite state automata knowledge came in handy as well.   Answer Question

Negotiation Details – Did not negotiate. The offer exceeded my expectations.

I applied through college or university and the process took 7 weeks - interviewed at Microsoft in February 2013.

Interview Details First of all, they went to my university for a presentation and I gave them my resume. A week later, I was contacted by email about scheduling a phone interview. The phone interview (about 20 minutes) consisted of questions like:
- How would you test a keyboard?
- What is the difference between threads and processes?
- Imagine that you get home and you find out you don't have your keys. What would you do?

Then I received an email about my phone interview and the process for an interview at Microsoft started. Microsoft pays for flights, accommodation, taxis and even your food.

I was interviewed by four different people. The interviews start with a few questions and at the end the interviewer comes up with a problem and asks you to solve it. Once you present your solution, he asks you to code it on the board.

My advice is that you should keep talking and pay attention to the hints the interviewer you give you. If he notices that you're doing something wrong, he'll probably make a comment that you can use in order to find out the problem in your idea / code.

After coding, the interviewer will ask you to come up with test cases for your code. He is probably expecting you to come up with many test cases, so think as much as you can about ways to break the code!

In the same week after my interview, I received an offer by email and accepted it.

Interview Question – Describe the most interesting project that you worked with and why you liked it.   Answer Question

Negotiation Details – I didn't negotiate.

I applied through a recruiter - interviewed at Microsoft in March 2012.

Interview Details Microsoft is really good through the interview process. I applied through my college recruiter. I had one interview on campus. It was fairly easy. I was told that I would fly out to Seattle a day after the first round. They contact you well ahead of time and send you detailed instructions about the interview and your trip. The interview process is well oiled. There are four rounds of interviews, with only the first one being easy. I was asked two questions each round. There were real world problems, object oriented design and run of the mill programming questions. The interviewers were a mixed bag, some helpful and some untalkative.

Interview Question – I was asked to design a program to read class attributes in a java file. This was a question I did not expect.   Answer Question

Negotiation Details – I had to travel internationally over the summer and Microsoft did not make a great job of accommodating that and my college calendar. I had a 11 week internship instead of 12 weeks.

I applied through college or university and the process took 4+ weeks - interviewed at Microsoft.

Interview Details I was recruited at college and had a quick one-on-one screen before being sent off to the Redmond campus for a full-day of interviews.

I interviewed with four different people at the same division (Microsoft Advertising). I had on average two questions per interviewer. The questions weren't particularly difficult -- you could tell they were not actively trying to weed out candidates. That said, they were somewhat tricky and required some thought behind them.

They were abstract questions that most students studying CS should be familiar with (write a program that finds the most frequent word that appeared in a long string, write a program that finds the shortest distance between two nodes on a tree). Because I was interviewing for an SDET position, it was prudent to show that you thought about edge cases and ways to test your program once you designed it.

After my interviews, I was taken back to their college recruiting building and given a briefing. I was not offered an internship on the spot, but they got back to me relatively quickly, after a weekend.

Interview Question – Given a 32-bit integer, return a list of all bit positions of that integer that are set to 1.   Answer Question

The process took 5 weeks - interviewed at Microsoft in December 2010.

Interview Details I had an on campus interview with Microsoft a few weeks after the Career fair when I had given them my resume. This Interview had only 1 pretty basic technical question. After that I got a call a week later that they wanted to fly me out to Seattle to interview with them there. I flew out there about 2 weeks later and there were many other people interviewing for internship and full time positions. The night before the interview they had bowling and food. It was pretty cool.

For the next day, we were separated into a morning group and an afternoon group. I was in the afternoon group which consisted of 4 45 minute interviews with various members of the specific team with which I was interviewing. Everyone was pretty personable and very helpful. Throughout the course of the interviews I was able to get a sens for the fact that I wasn't exactly what they were looking for, but not in a bad way. More of a, remember this for next time way.

The process took 1 week - interviewed at Microsoft in April 2008.

Interview Details Spoke to a recruiter and then was flown in for a 1-1 interview.
Had 3 rounds of interviews and a lunch interview. Very professionally conducted. Most questions in the first two rounds were technical. If they feel that the candidate is good, the interviews get over quickly. In all a very positive experience.

Interview Question – Questions on string manipulation and string handling. Questions on algorithms and data management. Questions on project and time management.   Answer Question
