The interview process lasted approximately 3 months, from early September to late December.

I applied via EDG online. About one week later, I received a link that asked me to answer questions about my background. This was recorded through the camera online.

Then, two weeks later, they sent me an online assessment. You were required to choose 2 of the following languages for the OA: C, C++, Java, Python, or Matlab.

After two more weeks, a phone interview was scheduled. They asked about OOP basic concepts, math questions, and code review questions (e.g., 'What's the output?' or 'Can it compile?').

Continually, after two weeks, an HR interview was conducted over the phone, focusing on behavioral questions.

Then, one week later, HR contacted me to ask for 3 references for a background check. They also scheduled a call to ask about my immigration status.

However, I was finally rejected. The process lasted too long.
