In today's environment, failing your first 121 training event should not be the end of the road. You might have to do penance at a small prop operation or mesa, but you might not.

Your problem may be how you are presenting yourself at the interviews:

1) Identify and address any OTHER interview or background problems you may have...read up on interviewing, make sure you look VERY presentable.

2) Make sure that you address the training problem correctly. Do NOT be defensive or blame your instructor, sim buddy, or the company, you will need to take responsibility for what happened. Sounds like you have already identified CRM and glass automation as issues...when asked, explain BRIEFLY what happened, tell them your plan for overcoming these problems, then SHUT UP. Hopefully they will move on to other topics.

Also do NOT let failed interviews get you down...it happens to almost everyone, and you may experience more than most. Just move on to the next one, I'm sure you'll get hired before too long. You are a better training risk than someone who has had never attended 121 training...you already know what you need to focus on, and will not be as lost as a newbie.

Someone mentioned eagle...they have a history of never hiring folks who failed out at another airline. Be aware of that, but if you get an interview you may as well give them a shot.

Also maybe try to get a multi-engine job. The One God, One Country, One Pilot, One Engine thing only works for viper people.
