> If they really just need someone to hold down a chair, they'll probably not budge. If they really want specifically you, they're more likely to bend if they believe that's their only move.
Except for super stars (literally, nerd famous people), 100% of companies and job offers will just let you walk away. One thing that I tell myself as a normie employee: There are many more people qualified to do my job than there are jobs.
As someone who has been involved in hiring, that's definitely not the case. The people I've seen who got hired are those who got through the interview process without any major red flags. There usually isn't any other potential candidate.
If there was, we'd try to hire both of them, because hiring is a long process, and if you find someone who seems good enough you want them on your team. You can always fire them during the trial phase if they turn out to be a bad fit.
