Octopus Energy Software Engineer interview questions

I applied to Shell, but I am getting redirected to write about Octopus since Shell got acquired. I submitted my application online and received and automated test which I believe takes about 45 minutes. They ask you a lot of multiple choice questions with what-if situations, then the tool sends you an assessment result where they write about your strengths and weaknesses. It all looked really good, but after about 2 days I was then sent an email that I was not selected to proceed to have a recruiter call. It all felt very impersonal and like you do the automated test for nothing, because even though the result is good you may get a general rejection response, without understanding why and no actual conversation with a recruiter, almost like when you simply apply but they don't find something specific in your CV a fit, only you spent an extra hour on an automated test that is possibly not even considered.

After a brief call with recruiter I was sent a technical test. I wasn't told until after completing and submitting the test that I was sent a test for the wrong role. The recruiter was very apologetic and shared that they were overworked and awaitng a holiday the next week. I prepared quite well and put a lot of effort into the first test however, and was quite burnt out and disappointed which made me drag my feet when I was sent the actual test I should have been sent in the first place. There was then minimal communication with the second recruiter, even after I asked for an extension to the deadline considering their mistake in the first place. Very frustrating interview experience, possibly the worst I've had.
