Came back to interviewing after a two year career break and the biggest gap wasn't technical, it was stamina

Refreshed the actual DSA knowledge in about three weeks, patterns came back faster than expected. What actually got me was sitting through a 45 minute technical round without losing focus, my brain just wasn't conditioned for that kind of sustained pressure anymore. Started doing timed mock interviews back to back, two in one sitting, specifically to rebuild that endurance rather than the knowledge. Felt silly training for stamina like it was a sport, but the actual interviews got noticeably easier once I did.
