Applied on the website, then got a phone interview after two weeks.

Asked two easy coding questions.

After three weeks, I was invited to NY to take the onsite interview.

There were two technical interview rounds, both discussed resume items and included two coding questions (not hard).

The third round was a discussion with a manager about designing software for stocks. After this round, I was asked to leave.

Overall, the onsite interview was not hard. Prepare basic algorithms and data structures well.

Nothing particularly difficult, but I'm not sure about the third round's question, as that was the round I was asked to leave.

Design a system for stocks: lots of stock information goes into the system, and customers are waiting on the other side for the stock system. How would you design this system?
