Constant engagement with employees, challenging job opportunities and compensation were the main reasons for such a high retention rate, Mukherjee maintained.

He said the wage hike this year will be averaging 7 percent in the country. "So based on performance, they (employees) will see a wage hike of 5-10 percent plus."

Salaries of employees in developing countries will go up by 4-6 percent, while those located in developed nations will see hikes ranging between 2-4 percent, he said.

The wage hike cycle will start this month. TCS has already given offers to 25,000 trainees and they will start joining from Q2 onwards, he said.

Stating that the joining ratio was also up at 74-75 percent in FY13 as against 60-70 percent in FY12, Mukherjee said the ratio in the current fiscal is expected to remain at the last year's level.

Country's largest software exporter TCS reported a 22.1 percent jump in net profit at 3,596.9 crore for January-March quarter, meeting market expectations.
