eBay Software Development Engineer In Test interview questions

started with phone interview. Asked some basic programming questions. had 2 F2F rounds. Both the interviews were easy. Here are some of the questions - 1. do u know shell commands ? ( stupid question !) 2. what are java exceptions ? 3. what design patterns did you use ? 4. what open source tools did you use ? 5. reverse a string. i thought eBay (Bangalore) had higher standards for interview. Interviews where not structured at all.....I guess they have inexperience people on board. I did't pursue the job after two F2F
