I had applied through nextstep portal of TCS since my college don't have placements. I prepared from campus gate (aptitude) site for online written test. For technical mcqs and C programs and email writing I had prepared from Internet. 10 days later results are out. For interview I studied C Java DBMS C++ and my mini project.They asked me to write a java program which I had tried and explained them how it executes. They asked me about my mini project and some general questions like tell me about yourself, are you willing to relocate, any questions for us etc.......There were 3 panel members interviewing everyone. 1 for technical 1 for HR and other for managerial rounds i.e 3 rounds in a single interview. After 2 weeks results were out by my college, but I had received my offer letter after 10 days
