Coding Technical Presentation
The whole process was super quick, like 2 weeks from recruiter chat to decision day. After a couple of phone chats, I got invited for the on-site. It was a packed day in SF, with lunch included. I had to give a presentation and met with 8 different people, from a UI designer all the way up to the CEO. They were keen to see if I was interested in the cybersecurity space, so definitely brush up on that and any recent security incidents before you go. Overall, it was a pretty clear process. I felt like I could really help with their current projects, so it seemed like a good fit.

Behavioral Technical Coding
Had one initial phone screen with the recruiter where they asked some behavioral questions. Then there was a technical interview with the team, which involved solving two LeetCode problems. Finally, I had an interview with my future lead where we discussed my resume. Everyone involved was very friendly.

Behavioral Technical
Got a call from HR first where we talked about my background and experiences, and they told me about the company. Then, I was sent a technical challenge to build two microservices for calculating social ratings. Unfortunately, they weren't happy with my submission.
Confirmed questions5 questions
- Can you create two microservices to calculate people's social rating?
- For the first microservice (data collector), please ensure it can: 1. accept HTTP requests with a JSON body like { "first_name": <text>, "last_name": <text>, "age": <number> }. 2. read a calculation seed from the application properties file (a random number between 0 and 1). 3. forward all information to a queue.
- For the second microservice (social rating calculator), it should: 1. retrieve messages from the queue. 2. compute the social rating score using the formula (score = base seed * user’s age). 3. output a message to the application console in the format "<firstName> <lastName> has <socialRatingScore> score".
