After reading through others' experiences, I don't know if this makes things more or less confusing on the assessment and the following interview invite, but this was my experience:
Bottom line: I took the assessment late at night and got an invite the next morning. I think this had more to do with timing than skill - and here's why:
I practiced CUT-E for an hour or so per day for about 4 days before I took the assessment. I spent the most time on sudoku, tube flying, and dot counting, in that order. Once you've learned the RMI/BRG, and the identical shapes tests, you've got them - no need to practice them much more.
Results during the actual DAL test:
I Performed less than I hoped on all but the RMI/BRG (easier than CUT-E), shapes matching (easier than CUT-E), and ATC (listen to all three transmissions until you're sure you've got it).
I maybe solved 4 sudokus. I decided to take extra time to solve each vs. guessing and attempting more puzzles.
On dot counting, it was a best guess based on the answer options and how many dots it looked like were there - you can count a little when they spread out, but still a best guess.
Multi-tasking: I thought I was still in practice mode on the multi-tasking when I discovered I was actually taking the real test after about 45 seconds (bombed it).
The tube was actually easier, I just stuck to the middle between obstacles and maneuvered ahead of my target hole at the last second. Still, not great.
Any other tests I'm forgetting we're a blur. Bottom line: Didn't feel good about it.
The questionnaire is where I really took my time. Basic strategy: I stayed close to the middle (slightly agree) because neither direction was good. There were a few where I ventured beyond a slight agreement, but only when the other option seemed really anti-teamwork or really anger-oriented. I tried to avoid anything that showed anger or temper, or that my opinion was more important than working with the team. I also avoided anything that indicated a tendency to manipulate others or solo thinking vs. team thinking. It's not easy, because they give you things that either make you look like a bad worker, or a bad person. I chose things like lazy over confrontational, if that helps. I also avoided sociopathic (using others to get what I want) type stuff. But, I was a Psych Major so maybe those just stood out to me.
Bottom line: I think the skill tests are there to get you worked up (with the exception of the RMI/BRG and the ATC). The personality/workplace behavior test is trying to assess your approach to working with others. Things like a temper, being overly opinionated to the detriment of working with the team, or manipulating people, seem to be a no-go for corporate psychologists. That's how I approached it - but I definitely took my time and thought through each choice WAY MORE than I worried about the skills portion
Anyway, I took the test at about 11:00PM and got the invite the next morning before 9:00AM.
I have no idea if the timing was based on some automated system, or if it was just the day they decided to send out invites to those who passed. From what I've heard, you could wait awhile after the assessment to get the invite. It sucks, but there seems to be no way to predict if you passed based on how long it takes for them to reach out to you with an answer. Some people are told immediately, either way, and others wait for awhile.
On the bright side, if you were invited to assess, you caught their attention. You'll either still be a candidate for DAL in the future or another great place will scoop you up. These companies need pilots. You've made it this far...
