The whole day interview started with a brief session with a HR rep followed by two one-hour tech interview sessions. One of the tech sessions was mainly centered around my talking about prior project experiences. The second tech session was a problem session where I was asked to go through the design and coding of line editor which needs to maintain lines of text to be deleted, inserted, searched & etc. I think this is one of the typical interview problems for SW positions. The afternoon sessions after the lunch with another interview consisted of another tech problem followed by a brief talk with the hiring manager.
