IIT Delhi - Indian Institute of Technology Answered Questions

Well, it is a myth that freshers do not have or have very less chance against the people with work experience. In some colleges there might be some points to be awarded for people with work experience, but I can assure you that most of the colleges including those that give weight to work experience have enough freshers in their batches and they enjoy special privileges for various opportunities being freshers.
The only thing is that for many interviews while calculating the composite score some colleges award extra marks for the candidates with work experience but freshers can cover those marks by performing good in interviews and securing good percentiles in CAT.

There is no provision for direct entry of International students in IITs. The Joint Admission Board (JAB) of IITs have recently decided that students from Afghanistan, Bangladesh, Sri Lanka, Nepal, Bhutan, Maldives, Singapore, the UAE and Ethiopia will be allowed to directly appear for the JEE (advanced) test, skipping the JEE (main) that Indian students have to take to become eligible for appearing in JEE(advanced) for seeking admission in IITs.

The only eligibility for CAT is to have a graduation degree or pursuing one. So I hope you are eligible for that.
PS there is a whole document on the CAT site where eligibility criteria is elaborated in detail you can refer to that for further assurance.
