The process took 2 weeks. I interviewed at Sysco (Columbia, SC) in Apr 2010
Interview
I applied on their website about 1 month before the interview. They emailed saying that they want to interview in-person. The interview was pretty basic. They asked questions such as "Tell me about yourself", "Why do you want to work for this company", "Have you ever encounter conflicts between co-workers and how did you resolve it?. They also asked a few basic technical questions like "What is this term mean", "How would you do conduct this research". They interviewer was an executive level employee of that company. After that he will explain to you the job description and salary. Then you can ask you questions. This person was very nice although did not seem very enthusiastic about doing the interview. In total, the interview took about an hour. After that, it took about 1 week to hear back.
I received two phone calls. They were short and asked behavioral questions. Interviewer was nice and it felt like a conversation. Each interview was about a week apart. I was followed up with a few weeks after the last interview.
I applied through an employee referral. The process took 2 weeks. I interviewed at Sysco (Houston, TX) in Jun 2019
Interview
The interview was pretty straight forward. For this position, I was interviewed by three separate interviewers. The first interview was simple and casual. Consisted of simple questions regarding personal background, education, experience, etc. The other two were a little more difficult as they were related to more technical aspects of the industry and the role itself.
Saw the posting on my university's jobs listing and applied through corporate. Got a call a few weeks later and asked if I was interested. The interview wasn't very difficult, and the questions were very straight forward. I was interviewed by two managers who would have been my supervisors. The atmosphere was really nice.
