My friend asked me to discuss a project together, but I am currently unemployed. I asked him when I would be able to join the job, and he said to me: It depends on the situation. What does this mean?

That is, you are still in a pending state, and you have no direct interest in him deciding to admit you. In other words, you cannot convince him of your ability at this stage, so you say it depends on the situation. The first is to stabilize your mentality and keep you between hope and disappointment. The second is to look at your next performance. If you make progress, then the chance will be great, if not, then it will be very small. This is just my opinion, you have to trust your own perception.
