Flipkart

First Round : OA contained of sql queries all are based on join operations and writing subqueries, one python script implementing logistic regression model by importing a dataset and print the final results using sckit learn and my friends got same sql questions but some were asked to implement knn,etc.. Second Round : In this round they have asked mathematics of all ai related concepts like pca process,activation functions related so be prepared with all those mathematical concepts of ml. Third Round : This is a ml pipeline building round where I was asked to build a end to end pipeline for a system where we should put links of flipkart on youtube videos like while you are watching a youtube video if some prodcut is there then we should predict that object search in flipkart database and put their link under the video as a ad.
