If you think leetcode is the worst part of being in this workforce - you live one incredibly privileged life. Wait until you have to deal with toxic management that exists in virtually every company and in virtually every leadership position. Wait until you have to deal with people who have a personal vendetta against you because of prejudice and will block any achievements you can make at a company. Are you excited for stack ranking? It exists at nearly every company and if it doesn't explicitly - it happens mentally. Are you excited to see incredibly huge churn in your industry? Are you excited to see the best and brightest constantly shutdown due to favoritism (and you will likely not be in that in-group)? Are you excited to watch people over the years lose all their hope and become soulless corporate ghouls who become the shill LinkedIn promoters that they themselves condemned a few years previously? Are you excited to work 60+ hour weeks to get PIP'd because that's just the way it is? (It will happen) Are you excited to put nights and weekends in at startups to see a round where the execs lose no value but your stock sees 3x+ dilution and no increase in value?
These are common problems at companies within SV. Leetcode is hardly a problem when you see how fucking terrible the rest is.
