Studying Leetcode is no fun to be sure. But, you'll never find a greater return on investment than preparing well and interviewing well. It often results in a major pay raise, a new and often better company, a new and often better project, sometimes a promotion.

Even better, the people that are the most averse to Leetcode cramming are often the ones that will see the greatest benefit, since they usually entered their current position with a single offer some years ago, and would be getting multiple offers in a very hot market today.
