Ecolab Logistic Analyst interview questions

3 interviews & 1 case study. Really professional environment; they focus on your work experience and how will you benefit them. Aptitude and personality test is part of the interview process

I applied online, got phone interview 2 weeks later, and an immediate on-site interview scheduled the first day next week. I feel good about the interview. But now, 3 weeks later, HR is not replying to my email.. I think they forgot me..
