How would you learn an ML model where you did not have many labels or was sparse
They have asked various basic questions from machine learning and Deep learning , Recommendation Systems relevant. They also asked two design various models from Recommendation Systems. One round was online coding from basic data structures.
NDA, cannot disclose.
Explain ICA, and CCA. How do you get to CCA objective function from PCA.
What data structure would you need for BFS?
Lots of behavioral questions, e.g. how do you resolve a conflict?
Five people during "in-house": One algorithms/coding, breadth and depth ML (one each), one ML architecture (recommendation systems), one "leadership principles".
The technical screening involved some leetcode style problems and general problem solving + ML questions. The round table was a mix of behavioral questions, statistics, ML, and at least 1 more instance of leetcode problems. Question difficulties ranged from easy, like "how to address in the dataset", to average difficulty questions like "explain the differences between and another" or "can you describe how works.
