How long should my job search take?
On average, 3-6 months. But it depends on your profession, geography, and level.
Back in the day, I submitted 92 cover letters over several years and got about 10 interviews and 4 job offers.
I know you have time constraints and financial issues, but you will get much quicker results by not just applying online. Find and make meaningful connections online and offline to help you get there faster.
