Database Developer – Top 10 interview questions and answers
Database developers are concerned with the production and maintenance of databases in accordance with specific coding standards. They also use database analysis to modernize and improve coding while eliminating inefficient coding. These processes involve scripting, troubleshooting, configuration, and debugging databases to streamline performance. They often work with other teams in order to get feedback and make suggestions that will produce the best, most efficient money-making procedures for the business.
1. What is involved in a typical database developer position?
Typical database development involves gathering data in order to identify trends that show vulnerabilities and improvement areas. The goal is to save money and make others’ work easier. It’s a process that requires immense attention to detail and creativity. In addition, developers are responsible for development of coding that will streamline business processes, as well as make data gathering and analysis more efficient.
2. What procedures do you use to analyze given data?
The process that I use to solve analytical dilemmas depends on the objective of the project. I begin by organizing the information. I look for relationships and trends in the data by establishing relationships between two or more variables. My procedures include data cleaning, data mining, quality verification, statistical computing, and analysis reporting.
3. What kind of data analysis software are you familiar with?
I have a variety of database analysis skills, including pivot tables in Excel, experience with software such as Java and Adobe, as well as data mining algorithms. My most important task in my previous position was to oversee, upgrade, and streamline our database to meet the demands of the company.
4. Are you prepared to take on a role with less managerial influence?
This question should be answered as truthfully as possible and you should ask yourself this question before interviewing. The employer is gauging how much you are willing to give up for the position. It should be known that stepping into a new position with a new company will leave you with less privileges than your last position. If you aren’t willing to do so, you probably shouldn’t be interviewing for that job.
5. Describe your proficiency in Microsoft Excel.
I am very experienced in many different areas of excel including various statistical formulas and pivot tables. I am very comfortable with Excel’s interface and am able to efficiently analyze given data as well as gather my own data and present it in a format that is easy for myself and others to evaluate.
6. What procedural improvements have you implemented in your company and what was the approach that you took throughout the project?
This is another experience driven question that has no specific answer. Don’t be afraid to go into detail about the project you are talking about. Consider it a story. Make sure that you give the impression that you are passionate about the project and what you accomplished during it. This is also a chance to show them your communication abilities.
SQL Server Database Questions
7. What are the new error solving commands introduced in SQL Server 2005 and beyond? What command did they replace and how are the new commands used?
The new commands are “try” and “catch”. From my knowledge, they don’t directly replace a specific command, but the “try” and “catch” commands have previously been used for the “raiseerror” command.
8. What commands were release in SQL Server 2005, enabling users to compare data sets from two more separate select statements?
The first command is “intersect”, where the final result is set where values in both tables match. The second command that was implemented is “except”. With this command, the final result is set where data exists in the first data set, but not the second data set.
9. Is it possible to directly import data from T-SQL commands without using SQL server integration?
Yes, it is possible to directly import T-SQL commands without using the SQL server. Six such commands can be used to directly import data into T-SQL language directly.
10. What are the capabilities of synonyms in the SQL Server?
Synonyms enable you to reference an object on a different server or database in your environment. It is a tool to simplify migrations without the need to make tedious coding or scripting changes. This feature helps minimize error, thus improving efficiency and saving money.
