Hi Folks,
Recently, I appeared for the Uber online assessment interview for an L4 position. The assessment lasted 70 minutes and comprised four questions. I found the questions challenging, particularly the fourth one, where I struggled to pass all the test cases. Unfortunately, I did not receive any feedback after the assessment, and I believe my performance was not good.
