I guess it depends on if they are interrogation style interviews or more of a getting to know you kinda thing. For my current job I had like 4 casual interviews and it was a blessing in disguise. I applied for a role that I was pretty tired of but had the most experience in. Without letting me know the first interviewers recognized that I had some skills that would fit well with a different position that wasn’t advertised on their homepage yet. In the end I was offered a job for the latter!
I know this is anecdotal and probably not how it usually goes. I also agree that 6-7 interviews is probably overkill. But multiple interviews aren’t always a bad thing.
Correlation != Causation
As others have pointed out we have better lives today because of scientific and technological progress not because of capitalism.
