Pros
Nothing. Never think as per Employee's perspective.
Kontras
Company is playing with Employees career.
I had been offer the Business Analyst position with Spanish language, I had been working with the big telecom company and accepted this offfer. I resigned from the current organization and served notice period. I was continously following the Infarsight HR to get me on board and after 10 days of leaving my organization HR informed me that they don't have the project for which I was selected and she is withdrawaling the offer letter. Now I am unemployeed and looking for the job.
I would suggest you all not to trust on this organization, if someone gets the opportunity.
