Greetings, Adarsh.

Most IIM's usually gives only 5-15 % of weightage to work experience (major weightage is for CAT score and PI) with points for approx. 24-36 months of work after which they don't count it ( which means work experience of more than 2-3 years will not give you any extra edge during selection)

Since you are an Engineering graduate, it is usually advisable to go for a technical job related to your field not just because it is easier to get but but because it is easier to justify in your CV. CAT values versatility but there is a fine line between versatility and randomness. What I mean to say is that if you go for a job which isn't even remotely related to your field of study then you'd probably be asked for reasons as to why you chose to do that. So if you were to go for a sales job after completing a degree in say, Electrical Engineering, you'd have to to explain your shift in career paths. To avoid such justifications and to to make the most of your CV, go for a technical job or maybe an Analysist position, anything which you can either link to your Engineering degree or to a Management degree.

Best of luck, Good day!
