The interview process began with two initial phone interviews, followed by a technical phone interview. The technical phone interview consisted of discussing my resume and answering two technical questions; I was able to answer the second question fairly quickly. A few days later, I received an email stating that they wanted me to interview on-site.

I flew out to New York, with airfare and hotel paid for, and interviewed at their main office in Manhattan. I received a tour of the office, which was amazing, and then quickly began the interviews.

The first round was a 2-on-1 interview. The interviewers introduced themselves and started asking me about my resume and projects. Both were very nice and open to answering any questions I had. They asked two technical questions: one algorithm and one design. I thought I did pretty well on these, though I ran out of time during the second question because they wanted to allow time for me to ask questions.

The second round was a 1-on-1 with a senior engineer. More questions about my resume were asked, and then we moved into rapid-fire, language-specific questions. I told him my main language was Python, but he insisted on asking me C++ concepts. He asked one technical question, which was fairly difficult, but I was able to mostly solve it.

After finishing, I asked the interviewer whether I should stay in the room or not. He hesitated but eventually said I should stay in the room, which led me to believe I had made it to a third round. He left and returned about 10 minutes later, informing me that he had made a mistake and that he had to walk me out. It was a bummer.
