Initial comunication was made by email, where they introduce themselves and made a brief about the job position they were trying to fill out, later in their email they made normal question in this part of the globe as: are you interested in the job position? which is your current salary? and would you like to join us? if so please respond and we will be back to you, please advice an appropiate time. The planning for the following interviews was neat, an HR representative call you and made the arrangements for the next interview, as well as they validate the information they have or they want to know as the one they requested in the introductory email, once they have it everything is ready for the real interview. It is normal that the guy you will for interviews you, key questions are with regards your experience and how do you face problems, they want you to have the drive in work.
