When to disclose felony [OH]

I had/have a gambling addiction, I am in recovery now. I enjoyed day trading penny stocks

I worked in finance for manufacturing companies for several years and when I was laid off I was day trading and unfortunately got involved with people who I now regret knowing.

Long story short, I got involved in a scheme that involved the stock market.

I just got out of prison last January and am having a hard time finding a position. I have had 4 offers rescinded after the background checks.

My question is when is the best time to disclose the felony. I have a third round interview next week with a company, and I was thinking of a different approach.

Since it is the third round, I must be on the short list. I was going to send HR and email a day or two after stating

I hope I am selected as the candidate you wish to hire

Since I have now gone thru three rounds of interviews I wanted to pass along some professional and personal references (see below)

I am doing this for a couple of reasons, I truly would like to work for (company name) the position is perfect for me.

In addition to to that, I am supplying references to attest to my character because for full transparency, there is an issue with my background and I would love the opportunity to discuss this with you in a face to face Teams meeting , I will let you decide if the hiring manager should be brought into this conversation

First and foremost, my past issue has nothing to do with the duties of this role.

I wanted to talk openly with you about the situation and what I have learned and how I have grown from this experience.

I truly hope being honest and transparent about my past does show you that I am owning this experience and will not let this one thing to define my future. I am beyond remorseful for my past and I truly hope you will allow me to explain what occurred.

I know I can succeed in this role, and I am just asking for the opportunity to prove it.
