Then for those jobs it is not reasonable to have 5 hour interviews, and I doubt they do since they care about costs. But the companies that started this trend pays extremely well, developers gladly jump through those hoops for those massive salaries.
"cushy" is how you describe it, huh? Well I chose to work in games so I knew I'd get the worst of all worlds working there, but I'd still keepo in mind
1. some workers are still doing full time jobs, some with families to care for. "a few hours" per app adds up quickly
2. SWE's are explicitly exempt from overtime in the US. And it's not unusual even outside of games to hear 50-60 hour work weeks. Or on-call roles. Probably even more in these times since company's "solution" to the economic changes is to lay off 75% of the workforce and triple the remaining 25%'s responsibilities.
3. it's not just top companies doing these hoops. Everyone copied the top tech companies without the top tech pay. 4-5 hours for Google is more than fine, 4-5 hours for some Law Firm that barely pays 60k in a high CoL area makes no sense.
