Technical Round: What is a flowchart? What is a Prime number? '1' is prime? On answering that '1' is neither prime nor composite, the interviewer asked me to prove what I said.And then asked me to write a code to find first 100 prime numbers. Next, he asked me to swap 2 numbers without using a third variable. He asked me about Industrial projects and the language I love. It was JAVA for me. He asked me if I know features of OOPS and asked me to explain class, object, inheritance, overloading with real life examples. At the same time asked me to prove whatever I said using code.
