They started out with an HR interview, as per the usual routine. This was followed by a technical screen over the phone. This consisted of a not-too-difficult coding question and some questions about my past experience.

The last stage was a four-round virtual onsite: two rounds of coding questions, plus one of system design, and then a talk with the engineering director.

One of the questions involved designing a simple C++ structure with an embedded array (private, of course). They then asked me to write an indexing operator[] for the structure.
