First interview was a great one. CTO was very friendly and approachable person. Second interview was very bad. I reached the office 10 min earlier than the given time slot. I pressed the bell for quite a number of times but no one answered. A guy happened to come out of the office but tell me to stay outside to wait and not to go in. My interviewer came out after 20 min later and i managed to go in the office. The interview was a lengthy case study presentation which i was not told in advance. Luckily , i did not schedule for anything that afternoon. Was given around 30 min to prepare for the presentation but ended with less than 20 min as the laptop provided can't access any office tools... They took aroung 10 min to fix it.
