I'm not really that desperate for more interview experience. I'm already juggling interviews with 7 other companies right now, two of them already at the final stage and another one close, and I'm expecting to get 2-3 offers within a couple of weeks. It's taken up most of my free time just keeping up with all of the assessments and interviews and correspondence as it is, I don't feel the need to spend another 2.5-10+ hours on Amazon (the assessment alone is 2.5 hours) just to give them a data point for why I withdrew that will likely be ignored anyway.
