Practice the coding rounds that actually decide a fresher or SDE-1 offer. DSA depth, clean implementation, and the communication habits interviewers score you on - online, free to start.
An SDE-1 loop is decided almost entirely in the coding rounds. Companies hiring at this band assume you have no production track record to point at, so they test raw problem solving: can you pick the right data structure, reason about complexity out loud, and write code that compiles and handles edge cases inside 35 minutes.
The failure mode at SDE-1 is rarely "could not solve it". It is solving it silently, jumping to code before stating an approach, or producing a working brute force and never being pushed to optimise because the clock ran out. Mock interviews fix that because the pressure is real and the feedback names the specific habit costing you points.
Practise here with the AI interviewer for volume, then book a one-on-one session with an engineer who has run SDE-1 loops when you want an honest read on whether you are at hire bar yet.
90 min
Two to three timed problems, usually easy-to-medium, auto-graded on correctness and runtime.
45 min
One medium problem in a shared editor with follow-up optimisation.
45 min each
Medium problems on arrays, strings, trees, hashing and two pointers.
30-45 min
Projects, ownership and how you handle being wrong. Shorter than at senior bands.

Most candidates plateau on solo LeetCode and need roughly eight to twelve timed mocks before the format stops costing them points. Do the first few purely to get used to talking while coding, then start treating each one as a real attempt with a score you track.
Rarely as a dedicated round. Some companies add a light low-level design question - design a parking lot, a rate limiter, an LRU cache - to see whether you can structure classes sensibly. Deep distributed systems knowledge is an SDE-2 expectation, not an SDE-1 one.
Yes. Fresher, campus placement, intern-to-full-time and SDE-1 loops test the same thing at the same bar. The behavioral round will lean on academic projects and internships instead of production work, and the coding bar is identical.
Sign in and take the free AI mock interviews: a DSA coding round that runs your code against test cases, an LLD round, and a behavioural round for the HR questions about your projects. There is no card and no limit, so you can repeat a round until the habits change. Book a live 1:1 with an engineer once you want an honest read on whether you would pass.
Usually "tell me about yourself" and your final-year project, one or two DSA problems on arrays, strings, hashing or trees, CS fundamentals - OOP, DBMS, operating systems and networks - and a few HR questions on strengths, weaknesses and why the company. The mock interview questions guide lists them with sample answers.
They are most useful for exactly those students. The first real interview is when most people discover they go quiet under pressure or start coding before explaining. Doing that in a mock costs nothing; doing it in a placement drive costs the offer.
SDE-1 is coding depth. SDE-2 adds a system design round and expects your behavioral answers to show scope and ownership, not just participation. If you are two to five years in, prepare for the SDE-2 loop instead.
Start with a timed DSA mock interview and get scored on approach, not just the final answer.
