OYO Software Engineer (Java) interview questions

Applied through LinkedIn, HR scheduled interviews. She said only 4 face to face round will happen so I didn't bring laptop. Once reached there the HR who mailed was not there. Other HR gave me age old office laptop for coding round on hacker earth. 1 hour 2 questions. Both were easy but unfortunately aftee 30 mins their WiFi stopped working. No IT guy present. Before they could fix WiFi, my hour was finished. They said I submitted only one question in 30 mins. (Btw that was correct, HR said). No DR rule like cricket.
