Preguntas de entrevista para el cargo de Software Developer en FlexTrade Systems Inc.

First took me through an intro call, which was simple enough explaining my career from start to finish. I'm a junior dev, so I focused mainly on my one previously role, talked about arch, day to day and core language uses and application. Recieved a private LeetCode link to complete within 7 days, was told 2 hours to complete but the LeetCode timer was set to 3 hours. Passed 4/5 test cases, took 2h27 to submit the single question. Did a bit of digging after submitting - found this specific problem was not public. Really enjoyed the challenge, but my code must not have been flexible enough (that fifth test case failing caught me so bad and I couldn't get my head round it annoyingly - big fluster). Did not receive next round invite.
