Even if you no longer ramble about your special interests (a common trait among autistic people), you still may fail to have a good conversational give and take. You may not be aware of the time structure of conversation, with both people talking some and listening some, and following some simple rules for switching whose turn it is to talk.
You could look at this by sampling some actual conversations. See if your phone has a voice recorder (most do), and record a conversation, maybe 5 minutes. Then, go back and listen, taking notes. You can mark at what point you start and stop talking, at what point the other person stops and starts, and what, exactly, happens at the transition point.
Some things to look for are both people talking at once, whether you or your conversation partner gives signals of attention without a demand for the floor, queries for clarification of a statement, and noises (might not even be words) of agreement with what the speaker is saying. Most likely you will see a change in how you converse, because the main point of the exercise is awareness.
This all sounds like a lot of work, but it will probably improve your social skills. It could also be something you can work on together with a therapist or an employment counselor, if you lack the focus to complete the task on your own.
