The interview process began with filing my resume for three of the groups that had open positions.

An HR representative contacted me to further explain their company and assist me in choosing positions. Following that, I could schedule an email-based code test. The code test included coding questions and lasted for two hours.

Once I passed the test, they invited me to their HQ in NY, NY.

During the one-day on-site interview, they questioned me about my background and interests, and presented some more coding questions.

The entire process took about one month in my case.

Technical problem.

It was in the email-based coding question. It asked about an algorithm question similar to the CLRS book.
