6 rounds of interviews:

• 3 coding/problem-solving
• Project presentation
• Hiring Manager
• Core value/leadership with another manager (Asked about my Java/SQL skills instead).

The whole process took more than one month. After that, I waited another month to hear back from the recruiter with little to no communication.

It's still unclear why they took so long to share the update and where in the process I needed improvement, knowing I was able to solve all the coding problems.

Coding/Problem Solving (credit card use case)

AI/ML coding: NLP use case that involves walking through how you would calculate word frequency (TFIDF), then what's the best method to measure vector similarity. Job description does not mention NLP.
