For this designation there was three round in total. the first was a normal HR round. where the just wanted to check my stability. if I'll stay in the company for a long time. The second one was the technical round. where they ask some DSA and Flask question The interviewer ask DSA in depth but they just touch the Flask. With the Flask questions it seems like they just wanted to know if I've ever heard about the Flask. the third round was with the project manager. who has ask some general questions related to the work I've done with the Flask framework and how this work and why we should use Flask. there was an additional round or you can say a discussion with the HR about the the offer and term and conditions of the work
