Applied online with a referral. You need a referral to have your resume considered. 20 minute behavioral round and that was all, only the single round. I received and accepted the offer.

Two round interview process. I interned for their Defense & Security sector as a tech consulting intern. Both interviews were about 30-45 minutes and behavioral and they sprinkled in a few technical questions based on the resume I submitted during both interviews. The bulk of it was behavioral though do not stress too much about knowing niche technical topics for the interviews.
