Interview Preparation Tips
Interview preparation tips for other job seekers - Recently, I had an interview experience that felt unprofessional. I was assured I was one of two shortlisted candidates for a role and encouraged to attend. After waiting for over 30 minutes, the HR representative finally conducted the interview but was dressed in casual nightwear, which left a poor impression. Such behavior from an HR professional does not reflect well on the company. I suggest researching thoroughly before investing your time and effort with organizations that may not prioritize professionalism in their recruitment process.
