Applied for a job through LinkedIn.

Went through a two-hour interview. Some questions were easy, like pass by reference vs. pass by value, but for others, I had no idea how to answer (e.g., Zed Engine insides).

The coding tasks were quite difficult. I solved one without help, but for the second question, I required some assistance from the interviewer.

Overall: No offer, but it was a great experience.
