How do I prepare for NITIE interview for PGDIE?

One of my friends recently got admission to NITIE. According to him, you should expect the following in the interview round. 

GD –

• The panel will consist of 3 persons (professors/ alums) and a group of 8 to 10 students will discuss any one topic. Topics will be related to generic or related to current issues.
• GD timings are set to 1 min initial time, 10 min discussion, 1 min conclusion/ summary.
• You can do 3 entries for 30 seconds each. 
• GD marks are given 60% based on communication skills, 20% group coordination, 20% knowledge.
• GD plays a crucial role in someone's selection. So, try to summarize the GD.
• In spite of giving only suggestions, put some facts and then discuss what you believe.

PI -

• The interview may take place for 5- 20 mins, depending on the number of candidates in that slot.
• Prepare a 1-minute introduction including your hometown, family background, your branch, college, final year project, summer internship, your hobbies, and achievements.
• Also prepare for technical questions (industrial engineering, thermodynamics) or subjects related to your final year project or internship. 
• There will also be some HR questions like why NITIE, your strengths, and weaknesses. 
• They will judge you based on your communication skills, and your interest in NITIE.
• Invest enough time while filling the application form as it will be a CV for the process.

Last but not the least, be confident and cooperative with the panel.
