I'm not sure about the size of the startup. But the smaller it is, the more should employees be onboarded to what the organization is trying to do. The environment should be inclusive as well.
If this happens, people would stay, even if the company struggles, and then further turn it into a success.
On a side note, the entire job ecosystem has been damaged. Most of the folks in IT fields (especially new engineers and new PMs) want to 'work' for money only, and hence the hopping.
The passion required got lost somewhere between 2019 - 2020 with the support of all the bhaiyyas and didis 😂
Now it's all about 'cracking the interview' and CTC jump upto 50 LPA from X.
I'm not saying that working for money is bad, but somewhere in between, there should be passion as well.
