My strategy is to prepare sql interview to solve 5 questions on a daily basis, which allows me to tackle 30+ questions in a week. This approach has been instrumental in helping me prepare for interviews. I start practicing SQL interview questions on platforms like Dataford, I always begin with easy questions. After solving 2 or 3 easy questions, I move on to medium questions. The amazing thing about the DataFord is that you can filter all the questions by levels such as easy, medium, or hard. If you want to practice specific topics like basic functions or window functions, you can choose questions related to that. What sets Dataford apart are their additional services like mock interviews, resume reviews, and 1:1 sessions. It's a one-stop-shop for all your SQL interview prep needs. #SQLinterviewprep

Are you preparing for the power bi interview? Then you got to read this.. When people prepare for the power bi interview, they try to remember the questions from the different blog posts. But I bet, that hardly helps for the interview. The questions listed in the various posts under the name of power bi interview questions are just the basic ones. Typically they are 'What' questions. In real life interview, you don't get much 'What' questions, but the 'How' questions. To answer the 'How' questions, you have to know the functionalities. There is no other way to it. Let me give you an example based on my experience. We all know the power bi pro license has the limitation on the dataset size to publish it to power bi service. If one has to ask the question on this topic, don't expect the interviewer to ask the straight forward question that what is the dataset size limit for power bi pro license? Instead, the interviewer might give you a scenario. He might say, the developer has a pro license and all the accesses to publish the dataset in the workspace on power bi service, but he is getting the error to publish the model. What could be the error that he is getting? This is the tricky question. Just having the knowledge about power bi pro license is not enough in this case. You need to think differently and try to understand the situation. We all know power bi pro license has the limitation on dataset size to publish it to the shared capacity which is 1GB. But just knowing it is not enough. You need to think accordingly and then tell that the error could be for the size limit, which is the correct answer. The point is, don't try to remember the questions for the interview, try to understand the functionalities and you will answer the questions on your own, no matter what the question is. #powerbi #interview

READ CAREFULLY 🖌🖌🖌 I have taken over Interviews of more than 50 candidates in last 2 years, where around 20-22 were selected. These were the 5 common things of those selected candidates: 1) Good at Power BI Service Level ✅ 2) Basic at Modelling and Intermediate at DAX & SQL ✅ 3) Tried to Fight back thoughtout 30-45 min of Interview ✅ 4) Confidence and Communication was good or gaved his best ✅ 5) Where able to Explain there Project, Daily Work & Agile Properly ✅ Note: I always ignore 20 % wrong answers in Candidate. Also if 10 questions ask he should give 7 questions answer and for 20 questions he should give 15 questions answer. 🔥 Work on this Guy's 🙏 It's Request ✌️ #interviews #itworld #itindustry
