      Written by William Swansen on April 4th, 2022

      How to Answer

      Requesting feedback from the people you work with demonstrates your desire to improve. Most employees avoid receiving feedback, fearing that it will be negative. By actively seeking it, you demonstrate both courage. A willingness to be open to criticism and initiative to improve. A good way to respond to this is to describe a time when you felt you didn't complete a task properly, and you sought feedback to correct your process so you'd do better next time.

      1st Answer Example

      "I have found that one of the best ways to improve myself is to continually seek feedback from the people I work with. Both my colleagues and my management team have perspectives that I don't and can spot weaknesses that I need to work on to improve. Therefore, I am constantly asking them about my performance, any suggestions they have, and resources I can use to improve my skills and expertise. I do this continuously, and it has been very valuable."

      1st Answer Example

      "Recently, my manager was away on vacation, and I was asked to fill in for them. A conflict arose between our team and another department, demanding an immediate resolution. The manager from the other department insisted we do what they wanted since our manager was not available. Knowing this was not the best solution, I presented an alternative and recommended that we discuss this with the senior leadership team to get their input. The other manager agreed. Working with senior leaders, we developed a compromise that resolved the conflict. When my manager returned from vacation, I briefed them on the incident, and they agreed I had acted appropriately."

      1st Answer Example

      "During a recent downturn in business, I was required to reduce my staff. Every member of the team was well qualified and valuable to the organization, so choosing who to let go was difficult. After a great deal of consideration, I decided to dismiss one of the more experienced workers, knowing that they could easily find another job within the industry with my recommendation. This allowed me to develop one of the junior staffers, increasing their skills and making them more valuable to the organization. I would make the same decision if presented with this situation again."

      Interviewers will ask this question for several reasons. The first is to confirm your qualifications for this role and your knowledge of the technology used in this job.

You pick a characteristic of one system, state its properties, and then compare it to the characteristics of the other system. Since the interviewer did not ask for a recommendation, you should avoid trying to discuss which of these you prefer or would recommend to the organization. If they are interested in your opinion, they will ask a follow-up question.

      Why the Interviewer Asks This Question

      This is a general question that the interviewer is likely to ask at the beginning of the interview.

      Why the Interviewer Asks This Question

      There are a large number of queries and commands used when administering an Oracle RAC database. The interviewers know this and will ask about many of these during the interview.

      How to Answer

      The worst mistake you can make during an interview is fabricating an answer. Interviewers are trained to detect this and will disqualify you if they think you are being untruthful or making up answers on the fly. If you don't know the answer to a question, admit this to the interviewer and then describe how you would go about finding the information. While this is not the best approach, it is better than being caught trying to mislead the interviewer.

      Why the Interviewer Asks This Question

      Even though the interviewer has already asked you about your backup strategy at another point in the interview, they may circle back to this later on. There are no rules about when the interviewer can ask you questions about the same topic during an interview. Interviewers will either group questions about a topic and then move on to a new topic or spread them out throughout the interview. You need to be prepared for both styles.

      Written by William Swansen on April 4th, 2022

      How to Answer

      Don't be surprised if you are asked about a topic you addressed earlier in the interview. Interviewers circle back to topics to either get more information or clarify an answer you provided earlier in the interview. They may also do this to calibrate your answers to see if you are being consistent throughout the interview. When responding to a question similar to the one you were asked earlier, try to remember your previous response so your answer will be aligned with it.

Interviewers will make notes of your answers and the terminology you use and then use this information for subsequent questions.

      Why the Interviewer Asks This Question

      During an interview, the interviewer will often use acronyms specific to the job. They use these to qualify candidates. If the interviewee asks about the definition of the acronym, the interviewer immediately knows that they do not have the experience or qualifications for the job.

      Written by William Swansen on April 4th, 2022

      How to Answer

      As a qualified Oracle RAC administrator, you should know most of the acronyms used in this profession. Acronyms allow you to communicate with other professionals more efficiently. Reviewing these before the interview will help you remember them and keep them fresh in your mind. However, you should never use an acronym in one of your answers unless the interviewer has already used it or you define it before continuing with your answer. One of the key skills you need to demonstrate during the interview is your ability to communicate complex topics to individuals who may not have a technical background. Using acronyms will make this more difficult.

They use questions like this to differentiate individuals who may have the right credentials for the job but not the knowledge, expertise, and experience. Every interviewer is looking for only the most qualified candidate to fill the position and, therefore, will use challenging questions to identify these.

      Written by William Swansen on April 4th, 2022

Even if you were to ace the interview and receive an offer, the job might not be a good fit for you if you don't have the skills and experience needed to perform the work. You would be unhappy in the position, and the employer would be disappointed in their hiring decision. Suppose you feel you are not qualified for the role for some reason. In that case, you should discuss this with the interviewer to see if they have a development program that would bring you up to speed or if there is a less demanding position available within the company.
