One of the biggest red flags when
hire Power BI developer is if they don't have a portfolio or previous work samples, which makes it hard to evaluate their abilities. Additionally, be cautious of applicants that find it difficult to articulate their methodology for data modeling or problem-solving in an interview. A developer might not be entirely qualified for the position if they have no prior familiarity with important Power BI technologies like DAX, Power Query, or data connectivity. Moreover, inadequate communication abilities or a reluctance to cooperate with others may impede their capacity to make valuable contributions to group undertakings and comprehend organizational requirements.
