0.1-1% hire rate based on applicants, or based on candidates interviewed? 0.1% hire rate of candidates interviewed doesn't seem compatible with your described growth rate, even if you very conservatively assumes you spend 1 hour interviewing each candidate, thats 25 weeks of straight interviewing per candidate hired. And thats 1 hour of time across the whole company, if you have 2 interviewers spend an hour each, thats now 50 employee-weeks, or an entire year. To double the company size in 5 years, you would have needed to spend 1/5th of your entire tenure interviewing. If you go up to 10 total hours spent per candidate (including all interviewers, recruiters, and time spend in discussion and negotiation) it becomes straight up impossible.
