Is there someone you trust who has been a mentor to you at one of your past jobs? Send them a note and ask them to mock interview you. People love being asked favors and for their opinion.
You sound unsure and defeated in your post. Were you feeling confident the day of the interview, or do you think you seemed desperate for the job?
I will say that all the best technical interviews I have had are ones where I spoke in short sentences, was able to end on a point rather than rambling, and left plenty of time in my answers to ask questions of the reviewer and demonstrate curiosity.
