Why interview practice matters more than interview knowledge
Most fresher developers who fail a technical interview don't fail because they didn't know the material. They fail because they'd never had to explain it out loud, under time pressure, to someone actively evaluating every word. Solving a problem alone in an editor and solving it while narrating your thinking to an interviewer are different skills, and the second one is the one that actually gets tested.
Static interview-prep resources (question banks, video playlists, a list of "top DSA questions") teach you the first skill, not the second. They also rarely match the actual role you're interviewing for: a fixed question bank doesn't know whether the job needs React specifically, or system design fundamentals, or SQL, so it gives you a little of everything and a lot of nothing.
The DevsUnite mock interview simulator generates questions from the actual job description you're applying to: technical questions calibrated to the stack and seniority level in the JD, and behavioural questions using the STAR framework real HR rounds use. It then gives you feedback on the specific answer you gave, not a model answer to memorize. You find out where your explanation was incomplete or unclear before a real interviewer does, and you get to fix it and try again as many times as it takes.

Why Mock Interview Practice Matters for Freshers
Most fresher developers fail technical interviews not because of lacking knowledge but because of lack of interview-specific practice. Practicing with AI-generated, role-specific questions before the real interview builds both the knowledge and the communication habits required to clear technical and HR rounds.
