what is Technical round in IBM Interview?

Technical round: Normally in this round some questions from programming concepts are asked, some about final year project etc. They can ask you to write some simple programs like, WAP to print next to the last word of a sentence, WAP to remove the vowels from the input string, WAP to convert uppercase to lower case and vice versa of a given string or sentence, WAP to print the desired character from string, WAP to reverse a string etc. 
The technical interview of IBM is relatively easy, a little preparation will work, if your programming concepts are clear and if you have sound domain knowledge.
