Questions were relatively easy at first and got more specific throughout. The interviewer, on the other hand, was extremely unprofessional and unpleasant. Instead of giving constructive feedback, lectured me on not being qualified enough for the role due to my lack of experience in the field and telling me to 'qualify myself' more in the next few months before applying for graduate roles (yet has reviewed my CV and offered me an interview?). Very unpleasant experience, would not recommend applying to the firm solely because of the recruiter (London office).
