A year ago, a recruiter invited me via LinkedIn to a phone screen. We had a one-hour-long chat, which was followed by a quick rejection, as I 'wasn't a right fit for any of the roles.' A few months ago, I started receiving messages from the same recruiter again. She wanted to talk about my new experiences, and after a while, I agreed to another call.

It was another hour of asking me about my previous internships and future goals (which are, well, strictly related to software engineering), followed by checking my knowledge of what Palantir does (I semi-quoted their website). The recruiter sounded deeply disappointed with all of my answers and finished the call stating that 'she has no idea why I even applied to Palantir.' When I didn't, she was bombarding my LinkedIn inbox for a year, claiming that I looked like a great fit (whatever that is).

In general, it was a very stressful experience and a huge waste of time.

What was the biggest challenge during my previous internship?
