Your Check list before you join a new company

 Before accepting JOB offer

Your career growth will always be in your hands. Your professional life will be successful only when you are extremely choosy about the company you join, business unit you join, the location you join, the type of market you have for the unit you are joining. I have a personal experience of disappointment after joining one company where i didn't notice that company considers April to March financial year where as i joined in June, i lost that whole year and i lost my probation period as it is not considered in your key performance indicators (KPI or KPTs) 

Check few things:

Connect to social media like Linkedin, Facebook and Glassdoor contacts of the company you join and understand work culture.

Do some google research on division or unit you are joining, it's market growth and prospects.

Understand the value and contribution of your division that you are joining.

Competition of the products and services your are about to handle.

Take home salary and Deductions are explained transparently.

Your grade in which you are appointed and hierarchy above to understand growth. 

Your work location office hours and Working days.

Your prospects in the team/division.
