This is life though right? These companies pay crazy high salaries -- they're not going to make it easy on you.
The fact that you'll barely be using the algorithms if at all doesn't matter. They use that for interviewing specifically because it's hard, and it screens for intelligence, problem solving speed, knowledge, and even how fast you learn (since everyone's got to learn the same algorithm question prep).
The end goal for them is that all their workers are at a minimum screened for the ability to grind at and break through difficult and esoteric problems, which are the biggest time sinks and therefore biggest limiters on the progress of the business.
