Experience: Was resume shortlisted, nothing great about that.
Tips: Keep up the CPI, but I guess it's too late for that now.

Round: Test
Experience: Test wasn't too difficult. Can be cracked if you're in your game and have a chill mind.
Tips: General aptitude preparation should be started atleast before a month from placements. Solve GATE papers, institute placement tests, read CAT modules and their tips for faster problem solving. English needs time for those who haven't used it much in their childhood. But still the difficulty level of questions in these placement tests is easy.

Round: HR Interview
Experience: Was  generally good. Interviewer was young and we could connect.
Tips: It is extremely important that you remain calm. You need to tame that nervousness down. Think of the interview as a general talk with a stranger. Be your natural self. That's when the ideas hit you for the questions you haven't prepared. Practice interviewing with friends and read about the most common questions on the Interwebz.
