1. Is there any interview tips which will be key focussed for Aramco?
2. My interview is VCI, so what are the most common questions they normally ask.
3. What are the replies which act as DONTs in Aramco.
4. Presently I am unemployed and looking for the job, will it be drawback for me during interview?

Please reply me as soon as possible as I have only one day left.
