I initially applied for a Senior position, after 3 interviews, I passed at the lower position (L2). I still accepted since the range was in my asking salary (80% increase)

then days after, they confirmed that my role is back to Senior. the pay stayed the same and still accepted it.

now I am having regrets of not negotiating it to higher base pay. could this be recruiter’s technique to lowball me?

I accepted the JO because:
- I asked to move my starting date 3 weeks further and they agreed right away
- I do not have certifications to offer. just my 10YOE and my performance during the interviews.
- I wanted to get out of my current company. I needed to secure this new job offer so I was afraid the role might be passed on to other applicant if I asked for a higher salary
- company is 100% remote

I just needed to vent this out as I can’t get the “what ifs” out of my head. but still need your advice for next time. I wasn’t a job hopper and I regret it as well. so I have no idea of the common knowledge during the job offer stage.

Asking for my senior father.

My father earned a decent, slightly above average salary years ago. He hasn't received any sort of pay increase in so many years that his salary has stagnated for so many years that he now earns slightly below the average and for the high cost area he lives in, he's now actually earning below the local poverty level. He's in an office -professional job that has dwindled as tech has changed over the years/decades. His work has technically increased because his coworkers have been layed off over the years and his pay has halved over the years because the have cut off his overtime and his on call pay (and his stress has increased because he's effectively on call all the time as a one man department overseeing a massive and critical portion of a major client).

For the last several years, his company (a major tech support company that's he's worked for almost 20 years) has been trying to lay him off -- going so far as to actually include him in a routine, mass layoff a few years ago before realizing they didn't have adequate redundancy for him.

Now, they are very clearly planning to lay him off again and have been pestering him incessantly for him to document his workflow.

This week, while on a call with his supervisor, once again being pressed for the necessary information to replace him, he finally got so fed up he gave his two weeks notice. His supervisor talked him into reluctantly retracting his resignation -- for the time being.

I want some advice about what he should do.

Company A initially discussed ₹10–11 LPA, and I now have another offer for ₹11.9 LPA fixed (₹13 LPA CTC). I want to negotiate for ₹13 LPA fixed, but they have asked for an offer letter as proof.

I'm uncomfortable sharing another company's offer letter and unsure why they need my current company's offer letter when PF details and salary slips are available.

Also, I initially mentioned a 60-day notice period to Company A, but my actual notice period is 90 days. My competing offer shows a joining date more than 90 days away.

Would sharing these documents create complications? Can I negotiate without sharing the offer letter? I don't want to risk losing this opportunity, especially since it's a reputed company.

Would appreciate advice from anyone who has experienced this in India!
