First round was well organised after being called by a recruiter. Was then followed up with a successful continuation to the next stage. This included writing approx 1000 word document split into 5 questions. Was then told I was unsuccessful due to lack of experience for an internship role.

8 Interviews, 2 with HR/ recruiting. 3 zoom interviews in 1 day and 3 zoom interviews in the next day. A person would need to take days off at their present job to be on these interviews.
- Where do you see yourself in 5 years?

The application process is straight forward. The company is quick to reply. When you are not invited for an interview, about 5 days for a rejection email from the time of submitting your application.
- Did not make it to the interview section but answered questions on the application.

Fairly easy interviews. Easy coding question to implement data structure and then a few conversations about my career. A few systems design questions and inquiring how I would handle different engineering scenarios.
- How do you handle weighing design decisions

Contacted my the recruiter via call for an on the spot screening and then placed into a process which was already running. A bit of an odd process in that I didn't meet the hiring manager but stakeholders from outside the function first.
- General competency questions on International HR and employment practice.

I applied through other source. The process took 1+ week. I interviewed at Fastly in May 2023
First meeting went well. Second meeting, interviewer came with questions that were so vague, no diagrams, not well thought out that it confused them as well as me. Gave the impression they weren't over concerned with being in the interview, and seemed bored to sum up the experience. I can understand why they are struggling to fill these roles when they have managers such as these responsible for hiring. I'm glad I found this out prior to working for this company. My advice if you have multiple options available to you, steer clear. Best part of the process, reaffirming how good I have it where I am.
- None really, just my previous experience. One specific question which was so vague, it was confusing at best.

30 min Phone call w/ recruiter 30 min video call w/ hiring manager Pretty basic questions about background and experience w/ data modeling. Feedback was given back fairly shortly after interview
- Questions about background and experience

The interview process was facilitated through a recruiter, the one-on-one with the hiring manager was done through video interview. Overall, I thought the process was positive though final decision transparency was lacking.
- Describe your experience with technical accounting research and memos.
