Hello aanchalsinha, thanks for your question.
Your 580 is not an insurmountable challenge, but it is definitely a challenge. My general philosophy is that your quants (e.g., test scores, GPA) open the door, but your experience and essays get you admitted. You would just have to make sure your essays really differentiate you.
In terms of general level-setting, check the mean or median GMAT scores of all the schools you’re interested in. The closer you are to the mean, the better. I usually say if your score is within the middle 80% range, you have a shot. If your score is lower than that, it’s not impossible but you’re facing an uphill battle.
Best of luck,
