I was contacted by Oracle RRHH by email and asked if interested in this position and an interview with the manager. I had this initial interview with the manager by phone and he asked about my past experience and an overview of the platforms and tools I've usd in the past. After three weeks I was interviewed at the Oracle office to do a technical test on paper. It was about unix commands, filesystems, permissions and basic unix stuff, another one was about algorithms and data structures. Another month passed and I was interviewed with a panel of three or four people also asking things about my past projects and some more in deep questions about filesystems, networking, configurations and so forth. Another month passed and RRHH contacted me and asked about my salary expectations. They used a very old email from 2016 which was pretty much out of date. Once i've told them about this new salary expectations they asked me for income receipts. At the same time I was also contacted by some external company to do a background check process which included personal references about my past jobs and colleagues which worked with me in previous projects. At this time I dind't have any offer from Oracle RRHH and they were asking me for some information that was related with a hiring. I sent them the "carta de no antecedentes penales" which was required for the background check and after another couple of weeks there was no news or offer. After another couple of weeks I was contacted by Oracle RRHH asking me if I was interested to apply to some other new position which was not this one. I contacted Oracle RRHH asking if this was normal, to have a background check in process and be interviewed to another position, also asked about an offer but I never got it from Oracle, I told this RRHH person that I was in a previous process with the System/Platform Administrator position and that I would be interested only if there was no interference with the previous one. They called me after a couple of days to tell me that it was ok to continue this new process. After thinking for this offensive process for a while I declined both of the processes. It was a completely waste of time and offends me as a employee and not sure if it reflects the company inside policies.
