Q1 : PrefixSum + querying

 You will be given the infinite queries of range [l,r) and nums, and find out whether this query range of elements in nums equal to the target or not.
Need to work for this large query set, asked optimisations and any further optimisation in querying

Q2 : Min path to reach end of a 2*2 grid with obstacles ( Binary Grid )

Passed ✅

Loop Rounds 🚀 - 3 C + 1 B + 1 S.D

Round 1 - Coding
Q1:
https://leetcode.com/problems/k-closest-points-to-origin/description/
Q2:

Tree Mountain View - Right View + Left View and handling the root element, cause it appear twice in RV & LV
Solution : Did Right View, then Left View and while building solution ignored root for once

TC - O(N)
SC - O(N)

Asked to do it in one single loop , still O(N) , Just Explained the approach, No time left

Round 2 - Coding
Q1:
https://leetcode.com/problems/simplify-path/description/?envType=problem-list-v2&envId=stack

• Asked to explain the Math behind it, what if its not origin ?

with CWD feature as well, struggled a bit to understand the question but
wrote the optimal code using Stack

Q2:

Won't remember, but from the top 100 frequent asked questions, around HashMaps

Round 3: Behavioral

• Interviewer is a director level individual who manages 40 people under him, Asked questions around conflict resolution, Project deadlines, Proudest Achievement
• Answers should not contain much technical, they wont bother and they only judge on how we managed those situations
• He also set 7 min timer for each question and expected me to answer approx 7mins.
• Tricky and tensed here, cause stopped me multiple times in between and asked not to go technical

Round - 4 - System Deisgn

- Asked about FB live feed, just like Instagram feed

• Went well

After week's time, got result - Reject ❌

They won't share any feedback and won't even care after the result

Tips from my experience

• SW has more scrutiny than DE
• Expects clean and optimised code without hints in one go
• Behavioral - they care most - has a weightage as coding rounds

OP community gave a lot to me, Its time to give it back, All the best for those who are in this battle !

***** At the end, All we need is one. YES ! ✅ ******
