I interviewed at a lot of these programs and heard about what it might be like from current residents. This is all second hand, so you should reach out to residents yourself! I don't think these programs can be ranked because they all have different vibes, but more so grouped based on academic to community. Look at the community vs. academic thread for more info!
Academic/ research bent programs: want people to do research, look for future leaders in field
-UCLA-NPI: primarily works with private population, resident-driven program, with recent bent on social justice driven by residents, lots of research opportunities, residents seemed happy, seems to have a lot of resources for residents
-UCSF: three-hospital system -ish, early outpatient experience, good reviewed research track, seems to attract a lot of md-phd/ more quantitative types, residents work more than average and can be burnt out/ outside of research track seems like less resources available
-Stanford: primarily private population like ucla (which has bothered residents), lots of elective time due to limited clinical sites therefore increased autonomy in residency and happiest residents I saw; for some reason, less research-y than ucsf; seems to have a lot of resources for residents
Seems to not really know what they are but are academic-y by reputation:
-UCSD: biologically-leaning, seems consistently disorganized in interviewing applicants for the past 2-3 years so leaves a bad taste, residents here work a lot and seemed burnt out, but at least it's in SD, the disorganization of the interview somehow outshines any concrete thing I remember about the program
"Academic and community combined"
-UC Davis: literally what they said is above; super chill program that might be too chill (residents leave inpt unit by 12-2pm), home call; limited research opportunities but there are people that do it (compared to programs above) as medical campus is separate (and far) from undergrad campus
-UCI: PD moved from UCDavis & focused on integrated care; seems more community-ish although research opportunities available
-USC: seems more community, only work at one site which is a public site with many staff that are burnt out; while might sell research on interview day, residents have trouble getting research projects; culture has affected morale of residency (see news from 1-2 years ago about cardiology fellowship)
Primarily community:
-UCLA-Harbor: primarily at one site, public hospital therefore lots of class and interclass cohesion, A/PD seems dedicated, know of burnt out/unhappy residents in first year due to call schedule
Didn't interview and don't really know:
-Loma Linda: know someone that really wanted to go here because of it's religious affiliation
-UCLA Olive View: know someone that interviewed here and their resident interviewer conducted it in their fancy car that they paid for with moonlighting money
-San Mateo: apparently super chill as all "call" is actually moonlighting; knew of a resident that lived in SF and commuted to San Mateo
-Kaiser Oakland: don't know much, but 2 year old program
-Kaiser Fontana: no clue
-Kaiser San Jose: also a 2 year old program, don't know much but for some reasons someone in their first first-year class left the program and during the 2nd year class, they couldn't fill their match list (which seems like a red flag to me)
-UCR: all the people that I met that ended up here wanted to be a psychiatrist in the inland empire
