Mistakes that kill applications
Generic CVs stand out at a <50-person company — and not in a good way. Fastest path to rejection.
Don't open with what you want. Open with what Castle is dealing with right now — is growing fast after their null round, and what you'd do about it.
The wait-and-hope strategy fails. Follow up on day five — response rates roughly double.
