Recruiter Call -> Phone Interview -> Onsite
Phone Interview:
Loved it. Enjoyed the real life game problem! Though it was me driving the meeting, working with the engineer (interviewer) felt like regular work.
On-Site:
TL&DR - It's your typical swe loop. Expect 2 - 3 DSA Interviews (Ranging from 2 - 3 Leetcode Mediums questions). And 1 System Design Interview (ExcaliDraw).
To be honest, the entire experience felt like navigating a minefield (defense ... fun). One misstep, whether in code or conversation, could set off a cascade of harsh criticisms. Acknowledging defeat and admitting limited experience in the sector did little to halt the relentless barrage of reproach. Basically you will feel your failure so I guess know your crap?
Overall, I didn't perform and couldn't adapt to the engineers. Sucks, the company is developing really cool products.
Advise - Do LC150 but know your crap. dsa, timers, os, back of envelop math, underwater basket weaving, etc. Expect a good grilling on-site. There's no help it's all on you. Doable with the militaristic mindset (I guess). Questions aren't hard.
