How do I evaluate this equity offered by a company?

Hi everyone, I would like some insight on how to evaluate an equity grant I have received at a company - they've offered a certain number of stock options at a certain strike price, and have also mentioned the price in the secondary market (what it is valued at, externally From there on, the recruiter calculated the annualized profit for the first year, based on the difference between the current valuation price - strike price. So essentially, (valuation price - strike price) * options. Now since the company is not public, I don't know how much to bank upon this profit - which the recruiter has factored in to the annual compensation. Apparently the price went up during the pandemic, and is now low due to the current market. I am also not able to fully understand the company's vision and strategy to see how the stock price can grow or devalue over time. So my question is: being new to this form of compensation, how can I evaluate the stock grant and propose a counter offer? Should I be valuing the options at a lower price than what they have valued it at? Does it make sense to ask for more stock options in my negotiation? I have no idea how the markets work, for all I know it could go higher or lower. I am also not in the US (the company is HQ'ed out of the US), so I'll need to look into taxation on the profits as well - assuming there are gains to be made. Lastly, the company had layoffs as well, recently. Is that a red flag? I'm a bit uncomfortable about why they'd lay people off and hire as well - though people in my country spoke about compatible time zones as a reason. Does this mean something for the company's burn rate, or strategy overall? No one mentioned this during the interviews. Thoughts, advice and some education would be much appreciated! Have a good weekend :)
