I appeared for an interview in Feb 2025, where I was asked the following questions.

  • Q1. ❌ Lack of Communication – Companies ignore calls and emails, making it difficult for candidates to get any clarity.
  • Q2. ❌ False Hope – They keep candidates engaged without any real intention of hiring them, leading to disappointment.

Interview Preparation Tips

Interview preparation tips for other job seekers - After clearing all the interview rounds, they ask you to upload documents and then tell you to wait. When you try to call them, they ignore you completely. Even after sending multiple emails and putting them in a loop, they barely respond. And when they finally do, they casually say that the position has been closed internally. This is nothing but a pathetic, disorganized, and highly unprofessional hiring process. These companies have zero respect for candidates' time and effort. They drag you through endless rounds, make false promises, and then leave you hanging without a proper explanation. It’s frustrating and mentally exhausting to deal with such companies. They create false hope, waste your time, and then vanish without accountability. It’s nothing short of a scam disguised as recruitment. Guys, don’t waste your energy interviewing with such companies. They don’t deserve hardworking professionals. Not only do they delay things unnecessarily, but they also kill your motivation and confidence. Avoid these time-wasters at all costs!

Interview Preparation Tips

Interview preparation tips for other job seekers - This interview was for the role of Head of Marketing role for Qyrus. This company and role is a red flag because they took 5 rounds along with a detailed assignment to create a marketing budget and plan for them. The interviews were taken by Jennifer Matos - HR Head, Vidhyashankar - Marketing Head for Quinnox, 2 rounds with the President of Qyrus - Ravi Sundaram and one face to face round in their Bangalore office with Chief of Staff - Rekha Raj. After each round I had to multiple followups with the recruiter - gaurav to get an update. Post the face to face round, I was given a confirmation that they are hiring me but now they are confused on the designation for the role whether it would be Head of Marketing or Marketing Director. Gaurav gave me a confirmation over call that he would be sending an email to upload documents within a day on 2nd of June. Post that they made sure I meet all important stakeholders whom I would be interacting with in the company.

Interview Tips & Stories

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.
