Opera Solutions Research and Data Analyst interview questions

First a simple online excel test which comprised questions ranging from applying vlookup to time and date functions. Then a simple aptitude round and cleared both test. Then first F2F interview..2 people started asking questions on my previous job profile and some elementary questions on my resume..went quite well..they were happy and told me that it will be a pleasure to get you on board(felt i made it at that point of time)..discussed about salary and commute means.. Then HR told me that I have a last round and if i end up clearing this one, they will lend me an offer Here comes the interesting part..three people entered the room and handed me a system..ask me to open excel and started asking weird and vague questions..one guy asked a question and when i started approaching and understanding the problem statement without giving me any time, the other guy threw a second question..they have no idea about how to take an interview and how to behave with a candidate..they confused me and i lost all my interest..they think they are smart but the reality is that they don't know the first thing about how to conduct an interview and how to behave..very rude people and organisation-This was my takeaway from this experience! Joined a better organisation later on!
