I received a phone call roughly a week after applying.

It was a simple phone interview on Hackerrank. The interviewer seemed very new, and I didn't really think he was taking things seriously. I was even more suspicious because my resume wasn't very strong. Furthermore, it seemed like they secured an interview for me relatively quickly.

Even stranger was that Palantir is notorious for asking very difficult or open-ended questions. I received a very simple question, followed by general commentary on my interviewer's work, some short questions, and a farewell.

They asked me how to take an input of several characters with a mapping to values and compute whether or not these character sequences equaled a third character sequence value.

Ex: A -> 1, B -> 2, C -> 3 Inputs: ABC = 123 BCA = 231

Result? AAA = 111

T or F: Does 123 + 231 = 111?
