I applied online and had an online assessment to complete right after. A month later, I was called for a phone screening by HR. The following week, I had a phone interview with two engineers. A couple of weeks later, I was offered to interview onsite by HR. The interview process consisted of giving a 20 min presentation on my qualifications, why Kellogg's, and why hire me for this role. This was followed by a panel interview with STAR based questions for about an hour with time for questions for them after. Then, there was another panel interview with more technical based questions regarding the role and current experience.
