Is Leetcode prep needed for interviewing as SWE or any technical position? Planning to apply for FAANG Data scientist positions. Also how many rounds of interview will be there ? TC - 160k(east coast)
Hiring for DS roles is not as matured as SWE, hence there is no industry wide hiring process. For sure you can expect atleast one round of LC.
Do Kaggle
Kaggle is good but will it help in an interview?
Depends on the company , normally it is one technical phone interview and then onsite. But some have a take home challenge and then one phone round and then onsite
There is a section of SQL on LC but less than 100 questions as if now. Apart from that there is interviewquery.com which you can subscribe to
