Interview Preparation Tips

Interview preparation tips for other job seekers - I had a terrible experience during the walk-in interview. Despite being called several times by HR to attend, there was no proper process followed. I arrived at 9 AM, but the interview didn’t happen until 4 PM. Meanwhile, people who came after me were interviewed within 30 minutes to an hour of their arrival.

I had already communicated all my previous experience and the gap in my resume in an email to an HR representative named Dona Cristel. She still insisted I attend the interview. After waiting the entire day, I was given just a 10-minute interview, which ended in rejection.

My question is: if everything was already discussed via email, why was I asked to attend in the first place? There were 150 people there, and I had already shared all the necessary details. Did you not read my resume or the email properly? Please, don’t waste anyone’s time like this.

Thank you. 🙏
