Assalamu Alaiikum.
About two years ago, I worked for a company for around two months. At the beginning, I did not know the company was involved in fraudulent/ scam activities. During my employment, I began to suspect something was wrong (around 50–60% doubt), but I did not have full certainty at first. Once I became convinced that the company was involved in scams, I resigned in a two week time.
During those two months:

• I received approximately 200,000 PKR as salary for my work.
• I am not sure, but maximum I made 10 people deposit, which made around $2,500 for the company via my work. However, after I handed them over to the Senior Rep, the company made them deposit much more money beyond that initial $250.
• I was not an owner or partner, just an employee.

Details about what the company did:
The company operated by generating leads through ads promising things like “100x your money with this trading platform.” When someone clicked the ad, they would enter our platform. Once a person made their initial deposit, my job was to call them and guide them about the trading platform (which involved telling some lies as well). At the end of this process, the person needed to deposit $250 into their account on the platform, and then my job was done.
After that, the client would be transferred to a Senior Representative, whom we had pitched to the client as an expert in future trading who would help them. However, in reality, what the Senior Rep would do is convince the client to deposit more and more money. When it came time for the client to withdraw their money, the Senior Rep would mislead them and convince them to make wrong trades, causing them to invest in the wrong commodity, and eventually their money would become zero.
My questions are:

1. Is my salary considered haram?
2. Am I required to return or give away the full 200,000 PKR?
3. Am I responsible in any way for the $2,500 the 10 people initially deposited (which I was directly involved in), or for the additional larger amounts the company later scammed from them which i dont know how much?
4. What is required from me in terms of tawbah or financial compensation?

Jazakum Allahu khayran.
