The recruiter and hiring manager interview were all fine but the technical interview was quite chaotic. The feedback I got was confusing, they said I hadn’t mentioned things in my answers - when I had, and that I had spoke about some things, when I don’t remember mentioning them. The interviewer’s seemed really distracted, adding to the fact they kept asking me about my experience at ‘X company’ that I had not ever worked at…the whole thing seemed muddled. After reading the company reviews I’m not too disappointed.
I applied through an employee referral. I interviewed at Kaluza
Interview
I was contacted by an RPO recruiter at Kaluza following a referral. The recruiter was polite enough, but the conversation itself was quite off-putting.
Very early on, the focus shifted to whether the company could “afford” my salary expectations. My expectations are aligned with market rates and based on my current public-sector salary, so hearing this from a private company was unexpected.
What really didn’t sit right was being told - at the initial screening stage - that I would likely need to deliver “perfect interviews” to justify my salary, and that I was more likely to be considered for a level below my current role (and below my current public-sector pay).
That felt premature and not something a recruiter should be pre-deciding before any technical assessment has taken place.
There were also some inconsistencies in the discussion:
* My fit for the company was questioned because my current role involves a lot of legacy work, with the suggestion they are “more greenfield” - despite my background including greenfield projects, and somewhat ironically given Kaluza’s core business is helping energy companies modernise legacy systems!!
* I was asked whether I was frontend or backend even though my CV makes this very clear
* The role was advertised in multiple locations but I was told hiring was effectively London-only when I mentioned Bristol
Taken together, the interaction felt much more like early salary anchoring and down-levelling than a genuine assessment of skills and fit. Also, the strength of the downward pressure this early did make me uncomfortable. In an industry where women are still too often low-balled, this kind of approach doesn’t create a great impression. Recruitment is a two-way street, and this process didn’t feel particularly candidate-aware.
I chose to withdraw. Funnily, I was contacted again a few months later by another recruiter but declined based on the earlier interaction.

Interview
I applied online and was contacted by a recruiter to schedule a screening interview in Melbourne. The interview itself went well, however communication afterwards was limited. Despite following up, I did not receive an update for several weeks, and more than a month later I received a generic rejection email stating that other candidates were a better match.
While I understand hiring processes can take time, a more timely update and some brief, constructive feedback would have been appreciated. The salary range discussed also felt below market for a Delivery Manager role given the responsibilities involved.
