I had similar stats and background as the OP, and didn't get into any programs my first year (no interviews either). I believe points 1 and 2 played a big factor. I applied to only selective schools, I checked with some but not all professors to see if they were taking students, and I didn't take that extra time to really tailor my statement to each school (from start to finish, not just by subbing in a "why this school, why this prof" paragraph). Another factor was that, despite 2 years of research experience, I hadn't yet presented at conferences or started work on any pubs.
This year, I fixed all of these things, and got accepted at multiple programs at all ends of the spectrum. My advice to the OP would be to find a few advisors who can take a look at your application and tell you what they think went wrong. You might want to have them do a mock interview too, in case your interviewing style (or clothing, appearance, etc.) is tripping you up. I agree with reluctantPhD01, with these stats you should be getting in somewhere.
With those credentials, you should be getting offers.
1) Are you making sure that the people you are applying to work with are taking students? Is your SOP really making a compelling case? You should be mentioning faculty in your SOP and really selling yourself.
2) Are you applying to at least 15-20 programs, some selective, some not?
3) Do you have strong LORs?
4) Are you a good interviewer? Do you dress appropriately?
5) How involved in research experience? Are you doing data entry for years or are you getting actively involved, taking a leadership role, writing papers, helping where you can, really taking a lead?
6) Is there a strong discrepancy in your GRE scores? You said you have a 1420? What is the Math and Verbal?
First of all, thank you to everyone who replied!!
To address the above questions:
1) Yes, both times I applied I emailed POIs ahead of time to ensure that they were taking students. I also thought both times that I was making a compelling case in my SOP, and had current grad students, post docs, and interns (5th year grad students interning at my research site) read over the statement. I discussed all my experience and also how everything I have done has led me to where I am and to pursuing a phd in clinical psych.
2) I applied to 14 the first year, and 18 the second. But what makes a program selective? In my experience, ALL clinical psych phd programs are selective. I applied to some more research focused (i.e. UCLA) and some more balanced (i.e. George Mason) and ones with all ranges of mean GRE scores.
3) I am worried that LORs may be where I am weak. I have only ever had professors and employers love me, but I don't know that I stood out beyond the one semester I was in their class, or above other employees. So while they only have positive things to say, I am pretty sure I don't have any "____ is the best worker I have ever had" statements in there...
4) I am a good interviewer, but my problem has been getting the interviews! I only got 1 the first year and 2 the second. I did well enough at one of the 2 this past year that I was first alternate, but the girl offered the spot accepted :-(
5) I worked full time for 2 years as a research assistant, where I coordinated studies from start to finish, and I detailed all of this in my SOP. I recruited, phone screened, administered IQ tests, neuropsych batteries, analyzed data, assisted with grant writing, IRB proposals, 2nd and 3rd author on multiple posters, and have 2 publications (not as first author, though).
6) I do have to admit that while I have always been praised for my writing skills, my analytical writing score was very disappointing-- 4.5. However, I have heard that the writing score is not very important. The split between my V and Q was not that great.
It really seems to me that it is the competitiveness of this program that is hurting me. I know that I would excel as a grad student, if only I could get in!
