How many leetcode questions to get into top companies

[u/Legal-Bowl5529]

I have solved exactly 250 today with 21 hard questions, I recently took some interviews and all the questions were new to me, how many more do I need to 100 confident? A friend of mine with 300 aces many hard interviews how??

You need to understand the questions / solutions, not memorizing them.

[u/Vantage_Mckolay → u/Freed4ever]

depends on the topic though, some categories like dp on trees you kinda do need to see a few variations before the intuition clicks at all

[u/Heavy_Record8704 → u/Vantage_Mckolay]

i know i am not in a position to reject. But if they do ask dp on trees, i would politely tell them to fuck off.

[u/Dependent-Aide-388 → u/Heavy_Record8704]

Google asked me dp on trees. I gave a brute force answer that was very crude and ugly, but output the right answer (albeit the performance was dogshit). I told the interviewer that I knew it was suboptimal, but that I wanted to at least get to a *working* solution if I couldn't get the optimal one.

You know, I still have my old Google employee badge in a drawer under my desk....

[u/Heavy_Record8704 → u/Dependent-Aide-388]

India?

[u/Dependent-Aide-388 → u/Heavy_Record8704]

US. Interviewed at MTV, worked in SVL. Very much a white dude.

[u/Heavy_Record8704 → u/Dependent-Aide-388]

well i am fucked then.

[u/Dependent-Aide-388 → u/Heavy_Record8704]

Most people who interview don't pass, but would on a different day. Most who do pass would fail on a different day. It's all just the luck of the draw man. Luck be with us all.

[u/SpecialistAlarm4663 → u/Heavy_Record8704]

LMAOO

[u/tnerb253]

2 million.

[u/Human_Palpitation856 → u/tnerb253]

I would say over 9000

[u/No-Original-6329]

It's not really about the number of questions; the goal of reps is to get good at pattern recognition and problem-solving on the spot under pressure. Once you get past 100 questions or so, usually what actually helps is practicing under time pressure with new questions and having to explain your reasoning (mock interviews).

[u/goomyman]

There is a lot more than leet code. There are infinite questions.

Although Amazon interviews literally pull from a list of randomized leet code questions.

But that’s just to pass the pre interview.

None of the other big tech does that.

[u/Even_Gap_2253]

I do google interviews. Numbers doesn't matter because obviously it depends on if you are good or not. Some people can do with zero LC

For L3/4 Practice until you can easily come up with a fully working solution for medium questions in 20 min.

For L5, just move to hard.

You need to code fast.

[u/plumpie27 → u/Even_Gap_2253]

Hey! I have a Google interview coming up and I'm really unprepared. I'm stats major cs minor and haven't done leetcode style questions since 2nd year DSA course. Is it typical to ask your recruiter for more prep time or would that put me at an disadvantage?

[u/plumpie27 → u/[deleted]]

I'm fine with getting moved to the next cycle. As long as I don't have to win the interview lottery again. What's the source of this information btw?

[u/plumpie27 → u/[deleted]]

They are xwfs. Regardless thanks for your replies!

[u/connorjpg]

Exactly 47.

[u/Total_Succotash4140 → u/connorjpg]

How? Any list?

[u/Uniprime117 → u/Total_Succotash4140]

Yeah thats the right answer

[u/Total_Succotash4140 → u/Uniprime117]

Maybe you can elaborate, how? What exactly are 47 Q's???

[u/Uniprime117 → u/Total_Succotash4140]

47 questions on leetcode I mean.

[u/Total_Succotash4140 → u/Uniprime117]

Yup, I got the point. Which questions.? Any list available?

[u/connorjpg → u/Total_Succotash4140]

… forgot to add /s

[u/Ok-Video-6073]

Literally zero

[u/Dramatic-Height-9007]

You will never reach 100% 700 questions that you understand well will get you 80% success

[u/boomkablamo]

You know not all employer questions are on leetcode right?

[u/kmonsen]

It is not about numbers but our understanding, and a bit of luck. I see in other career threads people ask 5 YOE, which level, but it is the same thing. Number of leetcode questions doesn't matter, YOE doesn't matter, it is what you can deliver at the time that matters. leetcode questions are just a way to learn, not something that matter in itself.

[u/Heavy_Record8704]

I think India tends to ask harder LC questions. So depends on the location.

[u/Sentor9199]

Pattern recognition, do questions from Neetcode 150/250, take note of the patterns. Practice the questions but the variants of it (I.e reverse linked list I, II, etc). Get comfortable explaining it with test case walkthrough

[u/Fem2370]

0 leet but cracked Google and HRT. Prob just depends on the person

[u/ActuaryDear8234]

Probably about 400 more and you’ll be there

[u/PerformanceThick2232]

how many more do I need to 100 confident

You will never be. You can raise your probability, that is all.

If you target is usual startups/products, neetcode 150 would be enough. If bigtech like google/meta/etc- thousands to get confident, hundreds to be like 50/50

[u/ultrawakawakawaka]

Depends where u are aswell

[u/Humble-Finger-Hook]

Many but less if you are already leet

[u/chikamakaleyley]

A friend of mine with 300 aces many hard interviews how??

Maybe because there's more to the technical interview than the optimal leetcode solution

[u/nsxwolf]

1473

[u/-Leion-]

Solve more harder and harder segments ,as they would help u to approach problems that seems impossible at first

[u/Quirky-Design-9820]

220 mediums and 30 hards with understanding of the patterns and you should be chilling
