SEAL and CEC candidates have to do an interview. That is why they don't necessarily list what they consider competitive. The CEC interview there are two write ups. One your recruiter receives AMD adds to the kit AMD the other gets sent to the board. The accession officer sits on the selection board and provides their input.
SEAL candidates. Recent change. If you are recommended, you go to an interview. They will ask all sorts of questions it is recommends to know current world events and have an opinion.
The other thing to know is which communities are selecting. Aviation is selecting like mad. Which means in about a year, it'll be super hard to get accepted. SWO use to be an easy one to get accepted to, not now. It's more competitive than aviation. Intel - if you know your congressperson. That's a bonus. Political letters of rec, a cultural experience or language skills are all to be highlighted in your kit.
