    Corporate Position Interview

    Anonymous Employee in Saint Paul, MN
    Accepted Offer
    Positive Experience


    I applied online. The process took 4 weeks. I interviewed at Ecolab (Saint Paul, MN) in March 2017.


    I applied for an Ecolab job online and then reached out to someone in HR to see what else I could do to help me find a role that suited my skills and interests. I was contacted and given ideas for various roles and departments. Once I applied, I continued to reach out to hiring managers and finally landed a phone interview. If they want to move forward after the phone interview, they will schedule an in person interview with the hiring manager and a few other team members. I came to St. Paul for my interview and met with a few different people. It was a comfortable, private environment and the interviewers were very friendly and easy to talk to.
