In the last three transitions I applied to a grand total of 5 companies.
Also, looking at the recruiter emails I've been getting, they've been ramping up over the last few months, and I'm back up to one or two cold emails per week.
But again, I'm fairly senior, and I have deep domain knowledge in a few key areas. I understand the market is brutal if you're early career or your knowledge isn't "T" shaped.
Around 12 calls if I remember correctly. With the exception of those who ghosted me, every company was very prompt, respectful of my time, and had a reasonable process that went from first to final interview pretty fast. I got a ton of outright rejections to my resume, which I sent around a lot. Getting the first call was the hardest part. YC job board ultimately led to finding my new role.
The company I went with had the best, warmest process that reflected how they like to work and was built to find people who had overlapping priorities. Thinking back, I think that most companies either deliberately or inadvertently wind up with processes that sync up with how they are organized internally and what kind of people they hope to hire.
