Interview questions [1]
Question 1
I got in as a fresher, so not much programming technical questions were askes as I am from non-CS backgroud. However , they did asked many quetions from my branch Biotechnology, which surprised me. eg. Who is the father of genetics? What are restriction enzymes?
There was only one interview round that combined technical, managerial, and HR discussions. The interview covered technical concepts, project experience, problem-solving, teamwork, career goals, and general HR questions in a smooth, well-organized process.
I applied in-person. I interviewed at Tata Consultancy Services (Lucknow)

Not too hard. Basic programming questions. Prepare the resume properly. Data structures and algorithms . The HR interview focus on your strength and weakness. Overall it was not too difficult.
