The technical round hit me with a grid search problem that involved checking for a word's existence using DFS. It felt challenging at first, but I quickly got into the groove. Funny enough, I had literally seen this exact question on prachub.com just a few days earlier, which really helped. Before that, I had a recruiter screen and a short phone interview focusing on behavioral aspects. After a couple of technical rounds, I received an offer, but ultimately decided to decline. Overall, a solid experience with technical depth.
