My son just did his alumni interview with his reach school. Since it wasn’t hard to do (in our hometown), I figured it might inspire him more to work harder on his essays. Most interviews happen in the summer or fall, so you are not too late, but she is applying EA/ED those deadlines are coming up fast. Just google school+interview and you’ll see the options. They range from on campus only for US students, to Skype, to local alumni interviews in your area.
Over the summer I drove son to interview at a lower reach, but still a reach. We were also visiting another school in the area. This worked out, because the interview went very well and I think it will, again, motivate him to work hard on that essay.
