one of the good HR consultancy reached me through naukri.com in 1st round, they shared with me a hacker rank test. in the test, it was contained 2 python questions. level of the questions was hard. in 2nd round, they asked mostly about python's different libraries. I was not able to answer much about python because I was good at ML algorithms. next, she asked me ML and stats that was a very easy question. these two interviews were taken by a third-party HR company. The last round was scheduled by Tigar analytics but I canceled the interview at the end moment because I received 2 offers from product base company.
