Nuance interview questions

Interviewer was pressurised in delivery and without any introduction he showed me two paper problem statements. No detailing about what is he looking for ? Had 15 mins discussion for problem statement and he left me to write a program in that room and continued his daily work. Hardly any interaction and to my surprise his logical level was very less and he was not knowing the technology I applied for. He was 5-6 years less experienced person than me and it was evident while I was explaining him my thought process about problem statements and his answers
