Automated LinkedIn Data Extraction, Periodic Comparison for Company or Job Title Changes and Updating the Changes to [login to view URL]  Currently there are about 350 public profile URL's of people on LinkedIn which need to be tracked. Requirements: 1. Data Extraction: The requirement is to extract the latest job title and company (The first one listed under the "Experience" section) from the public profile URL’s while being logged in to a specific LinkedIn account using an automated program which has to be developed. The output preferably will be written to a spreadsheet. 2. Comparison: The data extracted from the first run will serve as the base and the output from the second run (in about 3 months time) will have to be compared using a program which will have to be developed and in case there are changes, they need to be highlighted in a spreadsheet with some form of color coding to highlight changes - Either a new title in the same company or a shift to a new company. Also there should be a functionality to send alerts by email (which will be provided) for the contacts that have changed. For the third run, the output from the second data extraction will be the base and so on. Note: The number of LinkedIn public profile URL's may increase down the line as more new contacts are added to the database 3. Updating to [login to view URL]: Once the changes are tracked, these need to be updated to the [login to view URL] database (login details available) for the respective contacts. Title changes require a title update and a new company move requires the company name and the contact's title to be updated in to the database. Kindly provide feasibility either in steps or if all the desired functionalities can be implemented using a common program and timeline for completion
