UCLA Anderson is one of the top Business Schools in the US. Depending on the application cycle (Round 1, Round 2), the competition during the year, and the application volume in competing schools (USC Marshall and Haas), there is a high likelihood that you will be waitlisted if:
a) You don't have the required professional work experience (4-5 years)
b) You score below the class median (GMAT, GPA)
c) Your Quant score is below par (Remember MBA programs are quant heavy. You have to demonstrate excellence with your GMAT scores or your undergraduate quant courses)
d) You are from Arts/Creative arts background with limited Quant courses (also your GMAT Quant scores are not competitive)
e) Your profile doesn't stand out (limited community service, and leadership experience)
f) Your past successes are mediocre compared to the competing profiles with similar background (undergraduate degree, nationality, or years of experience)
The UCLA Anderson MBA Admission team has shared the waitlist guidelines for 2016 (Class of 2018). Here is a summary
1) Your name will be released only after a final decision or when you initiate a request to withdraw your name from the list.
2) There are perks if you don't withdraw your name. Say if you applied on Round 1, you would be considered again with Round 2 applicants.
3) The next round decision date will be the day when waitlisted candidate will be notified about the decision. If you are waitlisted in Round 1, look out for notification date for Round 2.
4) Don't spam the Admission team with updates. Use them sparingly as we have shared in the overcoming MBA waitlist post.
5) Don't expect individual feedback for your waitlist, but these are the reasons for your waitlist: Academic (Total Score: GMAT, GPA/Quant), Experience(Lack of Leadership) and Competition (Higher application volume).
