Redmond, WA (US)

I applied through college or university and the process took 6 months - interviewed at Microsoft.

Interview Details Hiring process took about 5 months. First interview was on campus at my university and covered behavioral and one technical question. Second interview was 2 hours on campus with 2 seperate interveiwers both covering technical questions. Flew me to Redmond, WA for final interview with 4 different interviewers. Offer given 2 hours later.

Interview Question – Implement a Find-Replace function given a string of text, search string, and replace string. Also a seemingly simple question became very difficult and complex when looked at through the eyes of a tester. A question involved writting a function to classify a triangle given its side lengths.   View Answer

Negotiation Details – Given one week to accept offer deadline. Terms were very favorable and I accepted on the spot.

Software Development Engineer In Test (SDET)
Dublin, Dublin (Ireland)

I applied online and the process took 2 months - interviewed at Microsoft in January 2013.

Interview Details I went through the phone interview with a recruiter and the coding interview with a technical person.

I was asked a few questions of my opinions about testing, a few simple technical questions.
- What's the difference of private, public, and friend?
- How virtual functions are compiled?
- What's the difference between linked list and array?
- What other data structures do you know apart from linked list and array?

In the coding interview, I was asked to solve two problems.
- implement strcmp() function, which takes two strings as parameters and compare if they are the same.
- Given a LIFO class, implement a FIFO class.

Interview Question – Are there anyone you know working in Microsoft?   Answer Question
