The first stage is an automated 90-120 minute Hackerrank challenge, a pretty commonplace initial hiring tactic, albeit very impersonal.

The second stage is a 15-20 minute personal interview with an HR Manager or Recruiter. They ask some questions about your previous work experience and its relevance to the position.

The third stage is a 45 minute - 1 hour technical interview with senior developers. Overall, they seemed pretty disinterested and uncooperative during the interview process. It felt like more of an interrogation than a mutual discussion of work experience. Then they ask some vague questions about C-style socket programming.

Overall, the team feels very old-school (and not in a good way). They seem to dislike post-C++11 STD libraries and Boost, preferring to develop in a more C-idiomatic way. They also don't practice Agile or SCRUM internally for development cycles and seemed to discourage long-term remote work after the pandemic is over. The hiring team seems very disorganized; I received automated Hackerrank requests for other positions I applied for within the same company.

Describe C style socket programming.
