I first met with Lubrizol members during an on-campus interview. They met with eight people from my department, and I was the only person they invited on-site, so I felt pretty good about it. The first thing I realized was that the on-site interview schedule they gave me was insanely grueling. I was to have five or six separate interviews in a span of 10 hours. I was also told that there would be a kind of "assessment" online that I should take the day before my on-site interview. I figured the assessment would be a kind of personality-based test. Nope! The online assessment was a collection of LSAT-type logic questions that I did not have time to finish. Like 50 questions that I only have 20 minutes to complete. I was completely caught off guard by this, and I have not encountered anything like it since then. During the actual interview, the vast majority of the questions were behavioral-based. "When was a time when you encountered a difficulty and how did you solve it" blah blah blah. I had stories prepared and I felt pretty good about my answers. My presentation seemed to go well, and they brought me out for lunch and dinner. I toured the facilities and talked with the chemists, and I was struck by how incredibly boring the actual chemistry seemed. I am an organic chemist, and this company makes greasy esters out of recycled materials. I understand that the additives produced by Lubrizol are important, but it seems like very basic chemistry that I felt frankly overqualified to do. Three weeks after the interview, I received my rejection call. At this point, I was expecting it. Why? Because Lubrizol CONSTANTLY brings people in for interviews as a "research chemist" and does not hire them. I know offhand two other people who were brought in for on-site interviews and did not get hired. My friend who works in pharma knows several people who got brought in and were not hired. Why would Lubrizol spend so much time bringing people in? Do they actually have a position to fill, or is this how they choose to spend their time? Three weeks after my interview, the "vacant" position was listed again online. I believe the open position exists to this day. Just know that if you get an interview here, it's highly likely that you are wasting your time.

very organized, 1 hour presentation followed by interviews. Each interview session was managed by two employees. one session, I went to the board and answered technical questions. the other sessions mostly focused on soft skills.

I applied through ACS career fair. Two people (one is research manager and the other is a chemist but not PhD level) interviewed me. They asked me to talk about my research first, and then gave me a quiz. The first step is Michael addition and the second step is transesterification, which is not difficult. There were also two follow-up questions. One is why bother to change from methyl ester to long alkyl ester. The other question is what's the role of this molecule. I think the answer is all about solubility and stability. It took me a moment to figure out the answers (I believe more context would help), but I did get the right answer after some hints. They were super nice during the whole process. I did have fun talking to them, but I got rejected after two weeks. I guess if you do not answer the question correctly immediately, you are done.
