This is all very interesting, but is complete fiction for most readers. 99% of job seekers aren’t going to receive competing offers from multiple companies conveniently at the same time.
I was lucky enough to have 3 companies that all gave me offers (a couple years back when the market for tech was at its peak). It played out like this article recommends. After an offer was on the table, the other 2 kept throwing better and better offers at me.
However, interviewing at 3 companies, over the span of 2 weeks, with an existing (remote) full time job was hard work. Likely impossible if I hadn't already checked out at the FT job. It was also mentally exhausting, with how companies like to do multiple rounds.
