How much can an sde earn in Trivandrum?

Is there any limit in Trivandrum

I'm unsure about the pay in detail. There are companies that offer good pay, but a good number of them may not be able to match start-ups pay on Bengaluru, or be it anywhere. But then the issue is that most of the high paying companies doesn't have an office in Trivandrum. But definitely a good place to live!

Payscale is generally lower in the south. Chennai/Kochi would be better if you are looking for better pay. But Bangalore can give you hands down the best money on the table so it really depends. Best case scenario would be to snag a remote opportunity from Bangalore or even US/UK based companies.

The general rule of thumb is if u are a salaried employee stick to big cities like blore/ncr/hyd. Companies are more, more opportunities, better pay. For salaried employee focus must be on pay not quality of life or WLB. If you want to start a business go to smaller places. You will reach profitability sooner.

I think currently Bangalore will be better

Depends on the company. Bangalore has more opportunities so more likely to have better paying jobs
