The actual test itself is not bad. The issues are:
1) They respond to your job application with an automated email where they share a link. No mention of the upcoming test being camera recorded, screen recorded plus microphone on.
2) Under this questionable environment, you are supposed to read SSML library documentation (which I had never used before) and fill in some missing functions. Reading the (large number of) tests serves as pretty much the only documentation, good luck with that otherwise. They mention that this is purposefully a highly abstract or ambiguous in terms of information provided task, to see how you do under these circumstances. Fine. But 1.5 hours?
3) LRUCache - again with lots of tests
4) Some string to node conversion
Overall the actual test is not difficult and actually quite interesting, they allow you to look for documentation as long as it does not provide the answers - thus screen recording and camera (they are looking at your eyeballs? However I felt so much pressure - as if they were didn't trust me. This made the whole experience awful. I would have enjoyed this and nailed it if this was a take home challenge without all the spying.
I understand - they are trying to avoid candidates copy & pasting solutions from StackOverflow or ChatGPT. I feel there are other ways of achieving an honest take-home test experience without big brother watching you.
