Stressing that the country's engineers should give back to society as it has invested in them, President Pranab Mukherjee on Wednesday said they should remember Mahatma Gandhi's talisman to arrive at correct decisions for serving the poorest of the poor.The President's advice came when a group of officers of the Indian Engineering Services (2013 and 2014 batches) and officer-trainees of the Indian Engineering Service (2015 batch) called on him at Rashtrapati Bhavan here."They should give back to society as it has invested in them. Besides, they should remember Mahatma Gandhi’s talisman of thinking of the welfare of the poorest of the poor in order to arrive at correct decisions. If they consider their job as a mission, they would be able to derive maximum job satisfaction," said Mukherjee."Engineers are engaged in key infrastructure sectors. India today has a large pool of technically competent engineers. We can be proud of what we have achieved since Independence," he added."Engineering service will provide the officers an opportunity to serve society and they will be entrusted with tremendous opportunities at a young age," Mukherjee added.
