I'm planning to do SIN-TPE-SFO, and some said if you check in on TPE, there will be a security agent interviewing you. I am not sure about connecting flights. I do have PreCheck on me.

So far, my experience is:
ICN-SEA, 2017, KE, connecting from SIN-ICN: nothing
ICN-HNL, 2019, KE, connecting from HKG-ICN: interviewed during transit, nothing too intrusive, interviewed again at boarding gate, and then I was sent to secondary and have my bag checked by a non-speaking English agent which took around 2 minutes (no SSSS, selected purely at random because my other travel party did not get such a thing)
HND-LAX, 2023, JL, connecting from SIN-HND: nothing

I am not quite sure about TPE, but my friend took CI and was going TPE-LAX in 2023 and according to her, she did not experience pre-flight screening whatsoever. I might be wrong, and since I am new to Flyertalk, I'd appreciate some insights. Thank you!
