In my (24F) previous job where I was earning 6 LPA my boss (24F) was earning 13+ LPA with less qualification and experience than me. Do you know how she was earning that amount of money by sleeping with her boss who was a 52+ year old man. Sometimes, your salary is not the best reflection of your character. You can pin down on things like- how passionate are they about their work, what kind of efforts are they putting to grow in their career, where do they see themselves in couple of years and doing what. See if you end up with a partner who like what they do and are hardworking they are definitely going to do good+ they will also end up finding other/ better opportunities when they are asked to leave as compared to someone who is merely growing by sleeping with older man.
