Green Hills Software Software Developer interview questions

HR screen followed by 4h HackerRank Challenge. Then 2 day onsite interview. First half of the day was just talks. You meet with the engineers, CEO, etc. Second half of the day is a 5.5h coding test. Pretty brutal. Language is C / C++ / Java. Cant say much because of NDA. I am not sure if there is a way you can prepare too.

I initially talked to a GHS recruiter at a campus career fair. They invited me for an on campus interview which consisted of going over my resume in detail and asking questions. Next they had me complete a short take home coding challenge. Finally they flew me out for an onsite interview where they had me complete an extensive multi hour coding project
