Has gone into deep level and step by step. Cleared the first telephonic round and got call for F2F interview. They need a person with very good debugging skills rather than development experience. - What is memory foot print - How do you analyse the heap - how to fix out of memory errors when you don't even have heap dump. - How do you prove your code is not caused out of memory error to client. - How do you replicate out of memory errors with out heap dump. - Few questions on Linux procs - Serializable and externizable - compare and contrast - how do you compress the data when you are serializing - few multi threading questions, Intrinsic locks - How do you make sure that one out of memory error from one module should not cause complete application to crash?
