Microsoft SDE1 interview questions

I applied through an employee referral. The process took 1 day. I interviewed at Microsoft (Redmond, WA). 5 to 6 interviews single day 1 hour each. Coding-based. You have to code on the whiteboard. Prepare data structures, algorithms, writing code. The first 3-4 decide if the hiring manager is going to interview you. Out of the first 3-4, you need to try to nail them all.
