Octopus Energy Student Worker interview questions

They shortlist the CVs and send an interview call. But, unfortunately HRs did not have time to read CV in details and to know about current German skills of the candidate. At the end, she was not able to carry on the interview (she joined the meeting late also). Everything ended with disappointment. After that, I got email from another colleague of her about the same position. I was happy maybe they have decided to go on with my current German level. But, as soon as I replied to email, he asked me it was by mistake. Utter disappointment.
