Long. 6 rounds total for me from initial phone screen to last round. Hiring manager, director, panel, presentation, follow up call with hiring manager. Long process but worth in the end.
- Personality as well as situational (tell me about a time when). Presentation was a mock business review.

Unprofessional interview process, probably gives insight into how this company is currently run. Recruiting coordinator and recruiter ignored countless follow-ups, would send invites without the interviewer added and then abruptly cancel those invites only to send new invites with the same mistakes present. The recruiter and recruiting coordinator also scheduled interviews for times where availability was not provided.
- Describe past experiences that would suit this role

4 interviews, on the last interview I found out a deal breaking attribute to the role, the company is 99% Mac. Had they put this on the job posting, or mentioned it in the initial screening I would have never applied. Aside wasting my time the hiring manager, as well as the recruiter were rude and didn't respond to emails asking details of the position. Would not recommend if this is a taste of the companies overall culture and demeanor.
- Technical questions regarding an identity provider called OKTA.

The hiring and interview process was very professional, remote, and quick. I was extremely impressed with how they approached each step, the amount of follow-up I received, and the friendly culture of the team. Even though I was not selected, I was very impressed with how Fastly treats its candidates and with the friendliness of its staff.

Fastly's HR recruitment team is the best I had ever worked with. I was working with Cameron (a Staff Recruiter) who was my point of contact during the whole process. His replies were immediate, any updates were promptly communicated, and not for a single moment did I feel out of the loop or forgotten about. The rest of the HR team was on point as well. The process: 1. Phone screen 2. Hiring manager interview 3. Technical interview 4. Onsite (Zoom) - 4x "one on one" 1hr interviews Even though I did not receive an offer at the end, the experience was extremely positive. All of the interviewers were very smart, professional, and overall - nice people. Thank you for the consideration Fastly and the best of luck ahead!

Anonymous Interview Candidate
I interviewed at Fastly
The head hunter asked me many questions including my language skills and then I went to the first interview. However, seems the interviewer didn’t know that I’ve already explained my language skill to the head hunter and they wanted to hire someone native and had experience working in the market. She quickly declined me. It’s a bit waste of my time and roller coaster to me as if they are only looking for native speakers, they could be more clear about it.
- Self intro. Explain past experience.
