You might look to improve y'all's process by looking at datatdog's interview process. I have never felt more appreciated and well treated than interviewing there.
1) they always give feedback
2) they have more generic positions, get you in the door to some small filter interviews, and then shop you around to find the right team for you, instead of the reverse approach where people shotgun resumes across your company trying to get in the door. The problem with the recruiter and multiple HMs I talked to at stripe is they didn't seem to care about getting people to work at stripe, only getting people to work in their org which didn't have open positions for X.
3) incredibly quick and responsive through the process. My recruiter at stripe did this!
Love what you're doing for science, Take care
