Nowadays, a lot of recruiters ask for salaries. And even if you don't provide one, they will base it off of known salaries of other employees of that company (or your region). So they know the baseline, even if you don't provide the recruiters with one.

Increasing, the hiring landscape is becoming more hostile to us. I guess you got lucky (congrats), but I would not count on that. Companies are always out looking for cheap employees, and the power dynamic is almost entirely in the favor of companies. So I would really encourage (for OP) to make careful plans, backup plans, rather than rely on luck itself.

Also OP, we get you're exhausted from overworking. It's also ok to take vacation before you start your interview journey. Recharge a little, it'll make a huge difference when you're going into an interview headstrong rather than tired out.
