Apart from the depression other people mention, how do you do with problems on sites like HackerRank?
Personally I can not take coding problems in interviews that seriously. Surely, it seems to me, the point is showing off your thought processes, not actually solving the problem. Solving the problem might be a matter of luck - sometimes you happen to try the right approach, sometimes the wrong one. Or even having heard about some particular algorithm is luck, nobody can know them all.
One perhaps slightly more realistic variant I have seen was when they gave me the specs for an algorithm and I had to implement it.
Probably many interviewers see it as a "solve it or bust" thing, but then it is their loss.
