Looking for career advice

I am currently working at an early stage startup as a software engineer and have been working here since around couple of years full time and an internship prior to that. I am getting a decent salary and the work environment is also good.

But While I write this, I have started feeling stagnated and bored at work and feel that I am not growing in career. This is one reason that has led to me start slacking off at work and take long time to complete tasks.😓

However, I don't want this to continue and thus am here for advice. I am trying to apply to various companies but only to receive rejections. Not even getting an interview call. I am planning to prepare for MBA and the exam is in November. But since folks usually prepare for MBA alongwith job so it means I should continue my job if I want to do so which is another problem for me. I am even confused if I want to an MBA since only the product management role out of it attracts me and not the consulting/investment banking once. So I am not sure if I should even do an MBA. 😒

I discussed this with my parents and they asked me to leave job and prepare for UPSC. Honestly, I have some interest in the exam and the job is great as well no doubt but being 26 years old I am not fully sure of taking this call since it involves a lot of risk.

All this has been causing lot of conundrum in my brain and it would be really helpful if anyone can suggest any things that I am missing out or that can be simplified.🙏
