Technical Behavioral Presentation
The interview process moved quickly. I first got a call from the hiring platform I applied through. After a brief 5-10 minute chat with them, my application moved to Bulb. Next, I got a link for an online assessment. Once I passed that, I was invited to a virtual assessment. This assessment included several exercises to gauge problem-solving, prioritization, and phone etiquette skills. The day after the assessment, I found out the outcome.

Behavioral Case Presentation
Had a 10-min phone call with HR for a general CV check and to discuss my motivation for the role and company. Then, after 2 months on the job, I had a 1-hour consultancy-style interview with a senior manager. This involved a business case study that was numerical. I was given figures to use and build on in my answers.
Confirmed questions2 questions
- Regarding the case study, if presented with various business improvement options, how would you prioritize them based on their potential benefit to the company?
- Given specific numerical data, such as the cost associated with a developer implementing a particular improvement, and drawing upon your experience working in this role, please provide an estimation of the potential time and cost savings for the company.

Technical Other
First, there was a short 10-minute assessment, then a 20-minute phone call. After that went well, I was asked to come back for a 5-hour virtual assessment, which is unpaid. On the day of my virtual assessment, I waited for a link or a call or email about it, but I heard nothing. They didn't send a link, even though I bought a webcam for it. I woke up at 8 am on my day off (I work late, so I only got about 4 hours of sleep). I think this process is a joke, especially for a customer service assistant role, which is basically what this job is, and they can't even be bothered to reply.
