I applied through a recruiter. I interviewed at Roblox (San Mateo, CA) in Oct 2012
Interview
1. A programming test through Email, and it was from a website hold by the interviewer, all kinds of tricky programming problems.
2. A phone interview about your background and experiences. This one was nice.
3. On-site interview. Will probably start from a lunch with the interviewers, and then meet 3 to 4 people, one at a time, and 30 - 45 mins each.
Interview questions [1]
Question 1
How do you make sure a exe file downloaded by users will not be changed? (Ans: Added digital signature)

How do you add this hash code to the exec? (Ans: Use a magic number in binary data, and preserve a fixed-size space)
