I applied through an employee referral. The process took 4 weeks. I interviewed at ServiceNow (San Diego, CA) in Aug 2021
Interview
The interview was over the course of about a month. 3-4 Interviews. Great process, but long. First interview was a coding question in java where you'll need to write a simple java program. On-site Interviewed with multiple teams. Onsite had 4-5 engineers asking questions about my past achievements and accomplishments in detail.
Interview questions [1]
Question 1
What are some of your accomplishments at the last company you worked for? (answer in deep technical detail)
Applied online, received an email from the recruiter to schedule a chat.
During the first interview we had a pleasant conversation about ServiceNow products and my work experience. Unfortunately, it was not a good match since my experience did not match what they were looking for the role (e.g different tech stack)
Overall, the recruiter was very respectful and kind, so a positive experience.
