Distressed/HY credit trading desk analyst interview

Hi all, does anyone have insight into the interview process for desk analyst roles, particularly in distressed / special situations / leveraged loans?

I’ve just been invited to interview at a BB in London and honestly didn’t expect it. I’m currently a junior sell-side credit analyst in Europe (c. 1.5 years of experience, no UK visa). I already cover HY at my current job, but it’s mostly BB to B+ names. I’ve worked on some distressed situations, though it hasn’t been my main focus.

If anyone here has gone through interviews for distressed or special sits desk analyst roles, I’d greatly appreciate any insight or advice on what to expect. Thx!
