Provided you do well in the entrance test and following interview, yes you can get admitted.

Unfortunately no. Christ university requires a minimum MAT score of 600. Please try another entrance exam like February MAT.

Kindly look into the placement details in the link: http://www.adarshaimit.org/plc_details.php.

Yes, make a note of your percentile as well.

You are eligible for all kinds of MBA programmes and if you apply, you may get a call for the interview. You have all MBA options so if you are planning to apply, I would suggest MBA finance or EMBA. They are really good. Also, dual degree is a good option for you.

It depends on how much hardworking and lucky you are, there are packages with 16 LPA CTC (Cost to Company, means all variables and fixed, insurance and perks). The package can also go as low as 3 LPA, but the average package is 3.5-4.5 LPA. Lots of good companies will come for campus placement. What

A composite score of 550 or above in the Management Aptitude Test MAT conducted by AIMA in either September/December 2017, makes you eligible to apply. One more requirement is that you must have 50%+ in all the semesters of your undergraduate degree.
Hope that helps.

Sorry to tell you, but as far as I know, Skype interviews are not available, you will have to come down to Bangalore at the scheduled time and date. Even I had to fly 2000 KMs for just an interview that lasted for 20 minutes.
