Applied online via LinkedIn and got a message from recruiter that she would like to have a chat on phone. We talked on the phone about experience, what I am looking for, salary, etc. Later, She arranged a technical phone call. On a technical phone called asked questions on SQL queries, experience, and Big O followed by a technical test on Hackersrank. Hackersrank consisted of three simple questions. Done it will all test cases passed. A few days later recruiter came back by saying "unfortunately there were a few errors, so we won't be looking to progress further with your application. " This was extremely shocking that even though I saw all test cases were passed and the program I wrote was with optimal time and space complexity, they said there WERE ERRORS. This was a lie. I did not expect from a company like this. When I requested to double-check if this was done mistakenly or any detailed feedback recruiter told she will talk to the team to double-check. After a few weeks of chasing, the recruiter denied giving any more feedback. Horrible experience, unfair interview process lessons learned do go for a NAME especially "Oracle."
