Kapil's Advice on Friday, March 30, 2012 :
Working from home is mostly based on company policy. No many companies in India have adopted this policy apart from few MNCs like IBM etc. Even with company policy , Work from home option is available based on the type of project you are in.
More generally-
Work from home is possible at later stage of career when you are individual contributor to an assignment. And there is constant sync-hing up required. And your manager does not need to monitor your every hour activities.
During early career bcos one at start usually work in a team and team work usually require you to work together with constant communication.
Other constraints, could be companies may not trust to let its intellectual asset i.e software to shared outside the office as some client has this secured ODC concept.
