Three DSA platforms, three different jobs to do

On 6 September 2026 I tried to open LeetCode’s own subscribe page to check its Premium price and got a flat 403. GeeksforGeeks let me in without a fight and showed a monthly Premium rate of ₹749. InterviewBit didn’t even try to sell me anything on the homepage. That gap in how hard each site tries to charge you tells you almost everything about what LeetCode vs GeeksforGeeks vs InterviewBit actually means in practice: one is a subscription business, one is a course business wearing a practice-site costume, and one is mostly free because the free part is the whole point.

None of the three is wrong for every reader. They’re wrong for the wrong reader, and that’s a different problem. This post is the LeetCode vs GeeksforGeeks vs InterviewBit breakdown I’d have wanted before picking a subscription blind.

LeetCode vs GeeksforGeeks for FAANG-style DSA prep

If your target is Google, Amazon, a well-funded startup, or any company running a Hackerrank or CodeSignal-style online assessment first, LeetCode is the one you open. The problem set is organized by company tag and by pattern, the discussion threads under each problem are where the actual interview questions surface within days of someone sitting the loop, and the contest cadence (weekly, biweekly) gives you a clock to prepare against instead of an open-ended backlog.

GeeksforGeeks covers the same algorithms, and its written explanations are honestly clearer for a first pass at a new topic; I’d send a beginner to a GfG article on segment trees before a LeetCode discussion thread. But the practice environment is built for breadth across computer science, not depth on the fifteen or so patterns that actually repeat in FAANG loops. You’ll get more mileage per hour on LeetCode once you’re past the concept-learning stage.

We’ve already covered how LeetCode stacks up against two other assessment-flavored platforms in LeetCode vs HackerRank vs CodeSignal, and against a premium curated list in NeetCode Pro vs LeetCode Premium. I’m not repeating that ground here.

What that first post didn’t get into is why the discussion threads matter so much for this specific comparison. A LeetCode problem that’s currently circulating in interview loops usually has a comment within 48 hours tagged with the company name, sometimes the exact round, occasionally the interviewer’s follow-up question. GeeksforGeeks has a comment section too, but it reads more like a forum for people debugging their own solution than a live signal of what’s being asked this month. Neither is better in the abstract. They’re built for different half-lives of information.

What each platform actually tests, underneath the marketing

It helps to separate the problem bank from the pedagogy, because the two vendors made very different bets there. LeetCode bet that motivated engineers will teach themselves through repetition and community discussion, so it invested in problem variety, contest infrastructure, and a discussion layer, and comparatively little in explaining the underlying concept before you attempt a problem. Open a hard graph question cold on LeetCode and you’re expected to already know what a topological sort is.

GeeksforGeeks bet the opposite way. Its article-first structure assumes you might be seeing binary search trees for the first time, and it walks through the theory, a worked example, and only then a practice problem, often a simpler one than you’d find on LeetCode for the same topic. That’s slower per problem. It’s also why a first-year engineering student with no DSA background tends to progress faster starting on GfG than getting stuck cold on a LeetCode medium.

InterviewBit sits in between, though closer to GeeksforGeeks in spirit: short concept notes, then a problem, in a fixed sequence you can’t skip around in easily. The tradeoff is variety. You get maybe a tenth of LeetCode’s total problem count, organized so tightly that finishing the sequence feels like finishing a syllabus rather than chipping away at an open-ended pile.

Where InterviewBit actually came from

InterviewBit’s history matters here too, even if it’s easy to forget. The platform launched in 2015 as a coding-first alternative to Codechef and TopCoder, well before LeetCode had scaled its discussion community, and it built a loyal following among engineering students in India who wanted something more structured than a raw problem archive. It never chased the contest format that made LeetCode a daily habit for competitive programmers, and it never built the article depth that made GeeksforGeeks a reference site. What survived is the sequencing, and that’s still the reason it’s worth opening at all in 2026.

Placement tests are a different exam, and GeeksforGeeks was built for them

Indian service-company placement drives (TCS, Infosys, Wipro, Cognizant, and the campus-hiring wave every August through December) don’t test the same thing FAANG loops test. The questions skew toward aptitude-adjacent DSA, output-prediction, and language-fundamentals MCQs, often on a proctored portal that looks nothing like a LeetCode-style IDE. GeeksforGeeks grew up covering exactly this: its “company-wise” problem lists, its GATE-prep material, and its plain-English explanations of core CS subjects (DBMS, OS, computer networks) map directly onto what these tests actually ask.

LeetCode barely bothers with this segment. Its company tags lean overwhelmingly American and its problems assume you already know the fundamentals rather than teaching them. If you’re prepping for a mass campus drive rather than a FAANG loop, GfG is the better first stop, full stop.

There’s a second-order reason too. Service-company drives often run multiple rounds on the same day, a coding round in the morning and an HR or technical round in the afternoon, and candidates report that the coding round frequently repeats questions from previous years at the same company. GeeksforGeeks’ archive of exactly those repeated questions, organized by company and by year, is a genuinely different asset than LeetCode’s global problem set. It’s a narrower tool built for a narrower, more predictable exam, and narrower wins when the exam itself is narrow.

Revision under time pressure: the two-week case

Here’s where InterviewBit earns its place, oddly. It isn’t the deepest problem bank of the three and I wouldn’t recommend it as a primary tool from scratch. But its structured, sequential course path (arrays, then strings, then trees, in a fixed order with a completion percentage) is genuinely useful for someone with eleven days before an onsite who needs a forced march through fundamentals rather than an open library to wander through. The 800-plus problem set is smaller than LeetCode’s, and that’s a feature here, not a gap: fewer choices means less time deciding what to practice.

I don’t love recommending a platform mostly for what it lacks. But a smaller, ordered set beats an enormous unordered one when the clock is the binding constraint, and that’s the situation a rushed revision week actually is.

There’s a middle case worth naming: the candidate who has two weeks and a LeetCode habit already, but keeps re-solving problems they’ve already seen instead of finding new gaps. For that person, neither LeetCode’s endless list nor InterviewBit’s short syllabus solves the actual problem, which is knowing what you don’t know. A mock interview forces that in a way neither practice platform can, because a live interviewer asks the follow-up question you didn’t think to ask yourself. If your last mock was more than a month ago, that’s worth fixing before you fix your GeeksforGeeks vs LeetCode split.

What I found checking pricing on 6 September 2026

I went to each vendor’s own pricing surface rather than trusting a review site, because stale competitor prices are exactly the kind of thing that makes a comparison post worthless a year later.

GeeksforGeeks’ Premium page showed a monthly plan at ₹749. Half-yearly and Annual Premium options were listed with links to their own checkout pages, but the actual prices for those longer terms weren’t rendered in the page content I could pull, so I’m not going to guess at them here; check the page yourself before you commit to an annual plan.

LeetCode’s subscribe page returned a 403 to my fetch on the date above, which reads as bot protection rather than the page being gone. I’m not going to quote a LeetCode Premium price from memory or from a third-party review, so that number stays unverified in this post. If you want the current figure, open the link and look yourself; it changes often enough that anything I typed here would likely be wrong within months anyway.

InterviewBit’s homepage had no pricing page at all as of the same date. The core practice platform, 800-plus problems, a free mock coding interview feature, and an online compiler for multiple languages, is framed as free throughout the site. There’s a mention of “Fast Track Courses” that implies a paid tier exists somewhere, but I couldn’t find a page stating what it costs.

The feature matrix, built from what I actually saw

What I couldn’t verify and won’t pretend to know: LeetCode’s exact Premium price on this date, GeeksforGeeks’ half-yearly and annual rates, and InterviewBit’s Fast Track course pricing. If a reader has those figures fresher than mine, the comment section is the right place for them, not my guess.

A note on why I bothered listing what I couldn’t find instead of just skipping it. Most comparison posts on this exact topic quietly drop a number next to each platform and move on, and readers have no way to tell whether that number came from the vendor’s page yesterday or a screenshot from two years back. Marking a cell “not shown” is less satisfying to write than filling it in, but it’s the honest version of a feature matrix, and it’s the one you can actually trust when you’re deciding where to spend a subscription.

So which one do you actually open first

FAANG-style prep: LeetCode, with GfG articles as your reference material when a concept doesn’t click. Indian placement drives: GeeksforGeeks first, LeetCode second once the aptitude round is behind you. A revision week with a countdown clock: InterviewBit’s ordered path, purely because it removes a decision you don’t have time to make.

I’ll admit the InterviewBit recommendation is the one I’m least confident about; it’s a smaller, older platform and I don’t have data on how often its problem set gets refreshed. If you’re applying to a lot of these roles at once rather than prepping for a single loop, our Auto-Apply tool handles the sending and tailoring so your practice time goes to the platform that actually matches the interview in front of you, not the one you happened to open first.

One more thing worth saying plainly: the LeetCode vs GeeksforGeeks question isn’t really an either-or for most people reading this. Plenty of engineers keep a GfG tab open for the concept they’ve forgotten and a LeetCode tab open for the timed practice, switching between them in the same study session. The mistake isn’t picking the wrong one. It’s picking a platform based on what a forum thread said three years ago instead of what your actual interview loop tests this month, which is the whole reason pricing pages and problem sets need a fresh check rather than a remembered one.
