Interview Preparation Tips

Interview preparation tips for other job seekers - It's my advise for job seekers specially for who are looking for senior positions in WIN.
They are taking interview till final round & after selection HR Will give you verbal offer & They will hold you by saying you are selected & our system is taking time . After that they will release a new requirement at junior level or they will try for internal transfer of employees . After waiting 1 month when you will ask about the offer they will tell you that we will take more time so, that you can search or go if you have opportunity.
All these experience I faced at Jaipur location . No value of plant HR commitment. When you think you got selected here please keep a 2nd offer with you.

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.
