I applied online on their website for a position in Waterloo.

They called me for a phone interview and asked me 20 technical questions. Then, they invited me for an in-person interview. This step consisted of two parts.

The first part was a written assessment, half of which focused on Window APIs. I had never worked with them before, so I am unsure why they invited me for an interview. The second part involved meeting the team.

After this interview, I emailed them for an update but never heard back.

This was a complete waste of time and very unprofessional.

The phone interview had 20 short questions. For example:

An array of size 100 contains all integers from 1 to 100, except for one missing number. Find that number.
