Manjunath, it is impossible that you have no communication. You are asking question in the opne forum it means you have the skills - not many can even ask the question openly and best part - u r admitting ur weakness and u r ready to learn. Best solution is - practice - practice - practice. Now u need to find where and how - depending on ur own constraints and timings. All the best for a great career: C2C: Campus 2 Corporate: https://www.facebook.com/groups/a2cskills/
