I spoke with the company at my school's career fair and had a phone interview with them two days later. They emailed me later that day asking for a second phone interview the following week. After the second phone interview, they contacted me the following week to schedule an on-site interview for the week after that. Overall, the process from speaking with them in person at the career fair to the third, onsite interview took three weeks in total. Denso moved quickly and was accommodating throughout the interview process.
