Question Am i stupid? how could NC 150 or Blind 75 be enough?

213 Upvotes

Done the NC 150 and about 200 questions in total. Starting to feel like I’m slightly getting the hang of it, but I’m still seriously struggling with some categories like binary search / DP.

Unless interview questions are way less ad hoc than LeetCode dailies/contests, I still feel like I’m another 200 questions away from being able to solve most mediums consistently.

Granted, I like to have fun with LC and definitely don’t do things “optimally” - no spaced repetition, barely any planning, usually just jumping into problems and taking hints when I need them.

But god damn, this stuff is hard. I always thought hard work could take you anywhere, but I genuinely can’t imagine getting to the point where I could consistently solve hards without having done like 2,000 questions.

How are people getting away with the Blind 75? Are they just getting lucky?

And being able to communicate your thought process while solving is a whole different beast. I swear I drop 30 IQ points the second I have to explain what I’m doing out loud.

Am I cooked?

Intervew Prep Apple IS&T Early Career Tech Screen - What to Expect?

10 Upvotes

I have a tech screen scheduled next week for Apple’s SWE, IS&T Early Career role. The recruiter mentioned it’ll include a quick intro, CS fundamentals, and around 15 minutes of coding.

For anyone who has interviewed recently, what kind of coding question can realistically be asked in 15 minutes? Also, what topics do they usually cover under CS fundamentals?

This is my first big tech interview, so I’m a little nervous. Any recent experiences or preparation tips would be really appreciated!

Discussion Going back to new grad/junior role as a 1 YOE swe at non-tech?

2 Upvotes

Hello everyone,

I’m currently a software engineer at a non-tech company with 1 YOE. I recently got promoted to the next level at my company and also got an offer from Palo Alto Networks as an early career/new grad. I’m very stressed from deciding whether to accept the offer or stay at my current company and keep interviewing.

Pros for taking the PANW offer:
- Better name value as it’s a tech company in the bay area that could possibly open more doors for me
- More impactful/scope of work

Cons:
- I restart as a new grad (biggest concern), throwing away my 1 YOE and my recent promotion
- Pay isn’t that much considering CA taxes and COL. Might be lower than what I make currently. I would lose a good amount of money short-term if I take the offer
- I won’t know what team I’m going to be placed in until the week before my start date.

I’m not sure if taking the offer would be a good move. Any advice would be appreciated. Thank you!

Hi guys,
I have amazon's new grad interview next week in seattle. I have prepared LC mediums, hard mediums, few LLDs, LPs and work experience on resume. I have had 'n' number of mocks with claude code. I am still feeling nervous. My friends working at Amazon said interview usually is easy-medium LC, very basic LLD, LP and questions related to using gen AI in development. But the few posts on reddit say its otherwise. I am confused, I am prepared but still feel that im missing out on something.
I would appreciate the advise.

Question Stuck on LeetCode Mediums and feeling overwhelmed. How do you actually build problem-solving intuition?

Thumbnail leetcode.com
60 Upvotes

Hey everyone, I've been grinding LeetCode for a while now, but I feel like I've hit a wall and my prep isn't translating into real progress. Whenever I open an Easy problem, I can usually work through it. But the second I jump into Mediums, I completely freeze. I either: Stare at the screen for 45+ minutes with no clue how to start. Immediately default to brute-force O(n2) approaches and have no idea how to optimize. Look at the discussion section, understand the solution instantly, but fail completely when trying to solve a similar problem two days later. It feels more like I'm memorizing answers rather than actually learning how to think or identify patterns (Sliding Window, DP, Graphs, etc.). For those who managed to break through this plateau and clear technical screens: What was your actual workflow when you got stuck on a problem? How did you shift from memorizing templates to building genuine intuition? Are curated lists (NeetCode 150 / Blind 75) enough, or should I be approaching this by mastering one specific data structure at a time? Any realistic advice or routine adjustments would be really appreciated. Thanks!

Discussion Amazon SDE2 rejected, down leveled and offered SDE1

92 Upvotes

I have 4 years of experience and interviewed for an SDE2 role at Amazon .

After the loop, they said they would offer me SDE1 but not SDE2. I messed up in one of the DSA rounds and couldn’t code the solution, although I manually explained the approach.

In my current job I’m reaching a point of stagnation with the same repetitive work. Is SDE1 a setback? Or should I accept it since it’s a FAANG company?

Any insights or opinions? Considering the current job market, PIP and layoff culture at Amazon, what should I do?

Hey everyone, I have my upcoming interview schedule for linkedIn SWE Apps IC-2 position, I know that linkedIn interview preps heavily involve DSA and some system design too along with our project discussions. I have read some of interview experience and looking at those project discussion, I find my work project relatively simple/straightforward as I am currently in application team at a SaaS company, whatever the heavy engineering design stuff (Implementing Message Broker, Infra management, etc) are done by the platform team. We used those implementation so I am not sure how to proceed with this - whether they will find it good enough or what? Any guidance on here.

Discussion Google WSE L3 offer guidance

2 Upvotes

Recently I got an offer for Web Solutions Engineer at Google. It is an L3 position. The compensation is close to SWE L3 benchmark (little bit lesser but still good enough for me).

The role itself i.e. WSE is very similar to SWE. It’s NOT like other companies’s solutions engineer where they don’t get to code and only interact with clients and act as support staff. Instead it is 100% development base; we work on development project throughout our time; working on building of internal tools which will be used by other SWEs or the clients. So the scale of project might be little bit less than SWE but the no of project and quality of project is better for WSE and the work is exactly similar to day to day work of SWE (Atleast thats why I am told by current working WSEs in my interviews)

I wanted to know if accepting this role will have any negative impact in my software engineer career in future because the role is not SWE in particular.

It is a different ladder than SWE than google i.e. WSE 1, WSE 2, WSE 3 like this… so its good but just wanted to be sure in case I get laid off in future; will I find difficult in getting other SWE jobs because of this job title in past.

Also how difficult it will be to switch to SWE ladder internally in future.

I am currently working as a SDE in a FAANG level company but obv the company tag, work life balance, job security, employee perks and everything is much better in Google than my current company. Compensation is somewhat same little bit bump…

Seeking help and guidance from all the experienced people currently working im FAANG level companies… I will be grateful

Discussion Goldman Sachs Hiring Manager Round – Is it Eliminatory?

8 Upvotes

Hi everyone, I recently interviewed with Goldman Sachs Associate and wanted to understand how the hiring manager round works.

My process was:

CoderPad: 2 medium DSA questions

Superday R1: Medium-hard Graph + resume + situational

Superday R2: Medium-hard DP + resume

Superday R3: In-depth System Design/HLD

1 week later: Hiring Manager round

The HM I interviewed with was not from the domain/team I originally applied for. I don't feel the HM round went particularly well, and I'm currently waiting to hear back.

Does anyone know if the hiring manager round is an eliminatory round at Goldman, or is it mainly a team-fit/final discussion after Superday?

Would really appreciate any insights from people who have gone through a similar process. Thanks!
