Tessella Graduate Software Developer/Analyst interview questions

Submitted my CV and cover letter and within 24 hours, I found out I had an interview the next week. Travelled to Abingdon for my interview. The interview was long (hour and a half) and far more technical than they had made out (they told me it was an informal chat). He talked a lot and I found it hard to get a say in. Hardly talked at all about anything on my CV or cover letter.
