      Chemist Interview

      Anonymous Interview Candidate
      Naperville, IL
      No offer
      Easy interview

      Application

      I applied online. The process took 2 months. I interviewed at Ecolab in Feb 2014

      Interview

      Got interviewed by two people, one was the section manager, the other was the team leader. Interview process was very short. They asked about the description of what you do in your current position, job duties, etc. They didn't ask that many questions, it was more about explaining about the company and the job. They then gave you a tour around the lab.

      Question 1

      All the questions were easy, no stupid HR questions.

      Average interview

      Application

      I applied online. I interviewed at Ecolab (Naperville, IL)

      Interview

      Applied online to open posting, was contacted for interview which was entirely full. Disorganized interview process, and professionally disrespectful. Spoke over my answers to questions. No word back and job posting just became inactive. Assumed they went with another candidate.

      Interview questions [1]

      Question 1

      Standard behavior questions, mix of some light technical questions.

      Application

      I applied online. The process took 4 weeks. I interviewed at Ecolab (Minneapolis, MN) in Jun 2022

      Interview

      There was a total of 7 interviews, with all of them being over zoom. Most of the interviewers were late which left me with an unsettling feeling about the company's professional habits.

      Average interview

      Application

      I applied through an employee referral. The process took 4 weeks. I interviewed at Ecolab (Eagan, MN)

      Interview

      Four interviews, including one with each member of the team. I was a contract worker with them before, and they hire many people who are contractors. For this reason, I didn't have an initial phone screen. They used the STAR method of interviewing.

      Interview questions [1]

      Question 1

      Give an example of a challenge you overcame.
