What are the major areas to look at when you are a new employee in any firm?

You need to identify the following:-

Your role.

Your department weight into organization.

Your customers and how to satsify.

Your organizing skills and communication skills.

Feedback from your customers and collegues.

Observe the operational procedure. The way things are being done or run in the organisation. Different organisations have different ways of running things hence from there you can provide ideas or solution on how to improve things.

I am trying to figure out, if the company is well organised and has the structure to perform its everyday duties. If it has enough employees for its business and these are good professionals. And of course its manager,  if it has good qualities and is someone that you can trust.
