Tech Mahindra Software Engineer interview questions

It was good. They asked questions on java concepts like oops, collection, multithreading, output related questions. Also on spring and sql. Asked to write one program to reverse a string without inbuilt method

3 round of interview. 2 technical and 1 HR All related to your resume and tech stack which is mentioned in resume. I have good experience with them where interviewer start with basic and make you comfortable of stuck somewhere or you trying for the question he will make sure you don't get nervous
