Started by filling out an online application. Sent my CV and a cover letter. They got back to me a few days later with an invitation to take an online assessment. After taking the assessment, an HR representative reached out a day later to set up an interview with the hiring manager. After that, a few days later I had a panel interview with 3 separate people asking questions about my experience (using the STAR method- P&G calls it something different but same concept). After that interview I was asked for another interview with a potential colleague the next day. And then a meeting later that same day with the hiring manager and HR representative to discuss their offer. Expect about 4-5 hours of interviews total.
Although I declined, the team was top notch and the interview process was thorough. If you know your stuff and are qualified, you will most likely get an offer.
