Don’t jump just for a quick salary hike. Although changing a job may yield higher compensation in the short run, it will not increase your domain expertise significantly. And like all other bubbles, the India salary bubble will eventually burst too.
It is worthwhile working for at least three years in a KPO firm. It is also worth remembering that a “body is not a body” — humans are not fungible — and that it is the domain expertise that counts.
Because of the nature of the work, ‘soft skills’ are significantly more important in the KPO industry than in the IT or BPO ones, and these include presentation, leadership and project management skills.
