1,2,3 are good. In my last company, i had 6 month probation and no paid leave during that. But i stayed there for 3 years, 85% hike in first appraisal, 35% hike in 2nd appraisal.
But 4 is confusing, they should give ESOP from joining since they are calculating that in CTC.
5, No WFH is okay, since not all companies are comfortable with WFH. But working on Saturday is a RED flag. I observed the companies which expect employees to work on Saturdays are the companies which will also ask you to work outside of the working hour.
