It had three levels of interview, 1st round is technical round interview where you will be asked about mostly from ML , Python and Cloud Platform. Deep understanding of ML algorithm required. Expect few python questions and question on AWS or Azure . Having knowledge on Big Data (Spark) is advantage. 2nd round is a online test which basically had all questions related to Full Stack development , did not understood the concept of this test as you are hiring for AI engineer and giving test on full stack . And 3rd will be Techno Managerial round . Where you will be asked mostly from project part and DevOps part . But HR communication is very bad , they will not pickup your any call or will reply to your mail if you are trying to communicate them or asking for update on interview. 3 rounds took nearly 1.5 months and after appearing for 3 rounds there is no communication from them or any update from them . Very slow process and bad management.
