Very Rigorous selection process includes a third-party assessment, on-site visit, and onsite in-person interview. The Talent Acquisition Team of Ecolab is the best team I have seen. They have completed the recruitment process, including the seven steps of the interview process so fast and swiftly within 4 weeks. I have other company interview lead earlier than Ecolab, but Ecolab team has completed the whole interview process very quickly and ahead of the other company that I was being interviewed. so I got the job offer letter well ahead of other company . Ecolab interview process started much later than other company but ecolab team has completed the whole process ahead of other company.
