i want to prepare for sr data scientist in MAANG companies. My background is in  core ML, deeplearning, nlp etc. 

I plan to target in around a year from now.

Does someone have any idea about the interview preparation or someone in these companies who would like to share some experience?

Interviewprep resource:

PracHub: Company specific interview questions

DataLemur: SQL Interview and Data Science Interview questions

StrataScratch: SQL and Python interview

Hi everyone, i am been doing dsa for sometime but never been to able to progress well as I'm not at all consistent.

Hoping I'll do well this time and preparing for a switch for next year. So have around 8 to 9 months of time.

Resumed my DSA prep with Binary Search Questions

Hey everyone, just released a small update for the LeetCode Contest Tracker extension!
Please let me know if there’s anything else you’d like to see added.

The extension displays (on the contest page):
Green tick → Problems solved during the main contest
Orange tick → Problems solved after the contest
Cross → Problems unsolved

New! Each problem now also shows its difficulty level (Easy, Medium, Hard) below the status icon.

Available on:
- Chrome
- Firefox
- Edge

GitHub Repo: https://github.com/altyon-get/Leetcode-Contest-Tracker
Feel free to fork the repo, add any improvements or features, and create a PR. If they’re useful, I’ll publish them!

Done with subset question with recursion, backtracking method
