The interview preparation can be an emotional and mental roller coaster for anyone, but with this tutorial’s help, we want to make your journey smooth to a MySQL interview. In this article, we have made sure to include the best possible study material for you, so that you can follow through to brush up on your skills and be ready for the interview.
Hence, we would like to remind you that preparing for an interview is not a shortcut process, generally, we need to start the preparation between 2-3 months prior to the interview. Although, if you don’t have much time before the interview or you just got to know that you have an interview within a week or less and have knowledge of MySQL, you can surely work with this tutorial as it compiles all the things you’d need to crack that interview.
So let’s get started!
Interviews for any technical role generally consist of two levels:
1. MCQ and Hands-on
2. Face-to-face interview
Both require a good amount of knowledge and projects related to the domain. In our case, we’ll be either sitting for an intern or entry-level role for DBA or MySQL developer. This will require a good understanding of MySQL as a platform and SQL queries.
We have also provided websites where you can apply for jobs, at the end of this tutorial.
Tips for Beginners
- Make notes: Keeping notes is essential for revisiting the concepts. Note-keeping doesn’t mean writing it all down, instead, it means you need to write whatever you understood in a concept and keep the crux of it as notes, to revise later. Try to make your notes short and write them in your own language.
- When studying, just study: When studying focus on the current topic and don’t let your mind wander. Staying focused is hard, but you can do it! Start with creating small tasks(for example, you are studying joins, so one of the tasks can be inner join, its application, and practical questions), and when you accomplish them give yourself a treat in the form of short breaks. If it’s a light topic, you can stretch for an hour but if it’s a heavy topic sit for a maximum of 30-45 minutes in a go, and after that take a 10-15 minute break. This technique is only suitable when you are studying a new topic. The topics you have already covered, don’t need this kind of attention as you’ve already understood them.
- Mark only what’s needed: We have a tendency to mark everything we have read in our first read itself. Instead, read a topic at least twice before highlighting something. It gives you clarity on what’s important and what’s not. First, make sense of what you’re reading and later mark the thing which is making sense to you and seems essential to remember.
- Practice, Practice, Practice! : Practice never kills, and the more you practice the more you’ll retain conceptually. So practice whatever you’ve learned, as you’re going for technical interview preparation, you’ll get a lot of practical questions. Therefore, keep practising, make your own questions, and ask them yourself.
