I applied online and later a technical recruiter invited me for a brief phone call. The recruiter was friendly and called me on time. During the call, they talked about their company and what was expected for their interns, as well as basic questions on my background/experience. But in the end, I decided not to move forward with the interviewing process.

I did a 45 minutes technical interview. The programming challenge about Hashmap implementation (C/C++). The interviewer will explain the problem to you first, but how to implement the Hashmap they want is challenging.
