Thanks Kah-King MSc. MIET,
Now this is very clear to me, thanks for all the comments, now i have seen the reqirements for CEng in the follwoinfg link with "UK SPEC"
I came to know there are competences requirement for CEng like A, B, C, D and E in "UK SPEC" which are needed to demonstrate for professional registration CEng during interview with evidence.
All the competency are needed to demonstrate one by one. This means just a Masters degree is not enough, I think previous work histry, research experience and leadership qualities are helpful to become a potential candidate.
I am agian thankful to all of you for useful comments and discussions.
