Four rounds. Ask a lot of meaningless questions. Not worth your time. * First round: Behavior * Second round: Coding * Third or fourth round: May ask to come onsite.

The interview went well. The interviewer was nice, patient, and helpful. However, I wasn't fully prepared, so I didn't answer all the questions properly. Consequently, I didn't get an offer, but it was a good first interview experience.

Online assessment: 70 minutes with two coding questions. The questions are not overly complex but train you to think quickly. They are especially useful for debugging your code rapidly. "Cracking the Coding Interview" is the reference book.
