Hey man, I would really push for getting a full-time offer at the MM firm you are working at now, that is by far the easiest option you have. If they aren’t hiring right now or can’t commit then I would really work on networking as much as possible. I summered at a boutique bank that couldn’t commit to hiring me because of their size: they only hired on a need bases but I kept following up with them throughout the year and eventually got a full-time offer.
Use your school network to get in touch with as many people as possible working at banks in Texas. Referrals are huge and an easy way to get a first round or informational interview. I would also start building out an excel sheet with all the Texas boutique banks and start cold-calling HR/Analysts. You should be able to put together a list of a few hundred boutique banks and possibly some restructuring/PE firms. From there try to reach out to as many places as possible: it’s a numbers game at this point.
A lot of the big banks are having a lot of trouble due to low M&A volumes so you might have a hard time getting interviews. I know BAML recently axed the entire Houston office – that was a few weeks ago.
Also make sure your resume is perfect, I’m sure it is. If it isn’t I know the guys here do a good job on their resume services.
Good Luck
