The interview process consisted of several stages. First, I completed an online aptitude test, which assessed general problem-solving, logical reasoning, and numerical ability. After that, I was invited to complete a Codility test, which focused on coding ability, algorithmic thinking, and writing efficient solutions under time pressure. I then progressed to the first-stage interview, which was a professional but fairly relaxed conversation about my background, motivation for applying, relevant experience, and interest in the Graduate Software Engineer role. I was informed that the next stage would have been an assessment centre, but I was rejected after the first-stage interview and did not progress further.
