Customer Profile:Our client is one of the leading data providers based out of Japan. They specialize in indexing data from job portals and identify the company’s tech expertise in real-time.

Solution:This client’s main concern was turnaround time on this project and getting real-time details of all the job postings. We built an expert team of professionals for this project to deliver in time with the highest accuracy level. They curated a crawler accessible through the web and capable of scrapping the job post depending on the client’s needs. The process is executed in two steps; Initially, the details from the listing page are scraped based on pre-set parameters. Then the scrapped list data is again imported into the system to get detailed information on each job post using the job post ID as the primary identifier. For maximum accuracy, we implemented an automated QA check to verify the records generated by the crawler to avoid duplication and redundant data. These efforts were appreciated in a great manner by the client.
