<human>: Can you give me a shortened version of the text?

Hi all,

I am coming to the end of a PhD in computational bio mechanics and have applied for a junior developer position with a software company in the UK. While my PhD is not directly related to the job, I have the skill set for a junior position as well as great communication and problem solving skills I've developed over the last 4 years.

I aced the phone interview with HR 2 weeks ago where I proved my knowledge of company and interest in the position. I had my technical test and interview with the lead developers on Wednesday last week and the morning after I had great feedback that the developers enjoyed talking with me and invited me to a final interview with the director of R&D this coming Friday.

I feel I am a great candidate for the role and I believe the people I have spoken to at the company agree.

My biggest concern is when I can start the job. The earliest I can really start is the 1st of September, almost 4 months away. I mentioned this in my application and confirmed it during the phone interview; albeit mentioned that I could potentially start a little earlier if absolutely necessary. I also confirmed 1st September in the second interview where they assured me that it is just so they have an idea of where I'll best fit in to their plans.

The company intends to scale up a lot over the next year (100+ people in all fields) so I don't know when how many junior developer positions they want filled and by when. I have been hoping my delayed start date shouldn't affect my chances of getting the job too much but I am a worrier and and I really want to know if it is a point of contention or not. Should I bring it up in the interview with the director on Friday? I was thinking I could express my excitement for the position, hence why I put an application in as soon as I saw the posting. I'd make him aware that I know 4 months is a long time that I would give an earlier date if I could. Then finally mention my concern that about losing the job due a restrictive start date.

Sorry for the rambly post. I'm just getting a little bit nervous right now.

Cheers.
<bot>: How do I approach the concern about the fact I cannot start the job for about 4 months in my interview on Friday?
