The Event Loop is a programming construct that manages asynchronous operations in JavaScript, enabling non-blocking execution.

Interview Preparation Tips

Interview preparation tips for other job seekers - Never ever join into this company. It is a waste company. which does not have ethics.
if you are in project safe (all projects are 3-4 months) else you will be fired without giving notice period (ie. immediate ). they don't have capability to maintain bench resources. simply running a company. Apart from me nearly 20 candidates are resigned . they forced to put papers.
One of the colleague (6-7 years in Photon) for her also not given any notice period. Asked her to leave immediately. So you can understand how bad this company is.

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.
