It was 2019, so things may have changed but I doubt it. Maybe I was lucky? Or maybe you were unlucky. I also applied as a Senior SWE (mobile) if that makes any difference. Out of the 12 companies I applied for I was given 2 hards (both were private startups), the rest were all mediums. >nearly 100 lines of code involving multiple steps I was never given anything even close to involving a 100 line solution. Are you sure this was even the correct/optimal solution? Either that or you're very unlucky. Which companies were asking such questions? >50 medium problems could span all of the possible topics. I was given problems that I hadn't encountered before, but I was able to solve them by deduction/critical thinking and applying the appropriate algorithms/patterns. Often the easy solution and the optimal solution weren't even that different, and just involved using a hashtable. Grinding through hundreds of LC to try and memorize/familiarize yourself with the solutions really isn't the right method. Have you read Cracking the Coding Interview? Gayle McDowell has some videos on youtube in which she explains her process.
