Applied online and received a response from the recruiter right away.

The technical interview was conducted by a senior engineer/manager, focusing on my resume to ensure I understood the discussed topics.

A take-home question was assigned, requiring a coded solution within 48 hours. This task consumed a significant amount of my time. The problem contained some ambiguities and misleading guidance from the proctor.

The problem purely measured skills in algorithms and data structures, with no software engineering assessment. It felt like a graduate school problem, despite the seemingly practical and realistic context.

I submitted a solution on time that met all test case requirements. Two days later, the recruiting team sent a rejection, stating that the solution did not match the coverage they were looking for.

The least I expected was a respectful acknowledgment of the time invested in the problem, possibly with an in-person call to discuss the solution's strengths and weaknesses. Please show more respect to your candidates!

Write an algorithm to cover a set of ground stations by a set of satellites, given coordinates and constraints on visibility/interference, etc. The problem is at least NP-Complete.
