Okay, let’s tackle this. So Diganta Das has 13 years of experience in sales and marketing, which is a significant amount of time. Location is Guwahati, Assam, India, which is a mid-sized city in India. Industry is not specified, but sales professionals in India can vary in salary. Considering his experience, I'll look at average salaries for sales professionals in India. According to various sources, the average salary for a sales professional in India can range from $3,000 to $6,000 per year. Let’s assume an hourly rate of $10 to $20. For a senior position like Senior Technical Sales Engineer, I'll estimate a higher rate, around $20 to $30 per hour. However, considering the lack of specific industry and company information, I'll take a conservative estimate of $75 per hour.
