Hello Arpit,

There is no such Minimum criteria to get a job.
However, atleast anything above 60 percent aggregate over 4years of Engineering is atleast expected such that you qualify for majority of companies and hence, you can participate for futher rounds.

Marks are important but just marks will never fetch you a godd job.

You need to have good technical Domain knowledge, Great communication skills, Good hand over aptitude and Psychometric tests.
Being abreast with current affairs and knowing well about the company you're interviewing with is recommended.
Also, a good command over group discussion rounds will come in handy when securing a good job.

Overall all paramteres havr equal weightage when it comes to Placements.

Hope it clears your doubts..!!
