Had two rounds of online interview with several managers. First, 30 min presentation about my background and previous experience. Second, they wanted me to prepare another presentation showing my understanding of their process/product. I was offered a process engineer position instead of senior process engineer that I applied for. After talking with HR and manager a couple of times, I decided to decline the offer. Basically, manager was not convinced that I am able to conduct job duties of senior level position but the example of task that manager gave was 1. not described in the job description 2. what I did have experience with. All other aspects of interview was pretty reasonable though and interview questions were within the scope of job description.
