First, a hiring manager called me and asked some general questions about my current work. They also told me about the position, expectations, and the project they are hiring for.

After that, they negotiated the time for a phone interview with me.

A couple of days later, I received a phone call from the tech lead. They went through some basic questions with me, such as what "volatile" is used for in C and what name mangling is.

Afterward, they thanked me for my time, said they would get in touch a bit later, and warned me that it could take up to a week.
