Very disappointed with the hiring process. Applying on their website portal is not at all useful. It seems posting a job requirement is only for regulatory or compliance purposes. The only way to get an interview scheduled is through a reference by a person with a designation. Even after clearing the technical, manager, and HR rounds, there will be no update or response. Calls or emails will not be responded to with the reason for rejection. Also, please get to know the salary requirements in the initial call and make a decision on whether to proceed further or not. It reflects poorly on the organization.

@HR team, the reason for rejection could be confidential; however, updating the candidate irrespective of the result should be the minimum you do. At least for senior positions, trust them to be professional and accept a "no" for an answer.

Simple basic DBA questions, job responsibilities, and scenarios.
