Welocalize Subtitle Editor interview questions

After I sent a CV, they wrote back the other day, sent a short questionnaire and requested a Skype audio call. They called on time and it took around half an hour. It was friendly and informative. After she hung up, she sent a pre-test comprised of four sections testing translation and localization skills, including some idioms. They give you 24 hours. I thought I was perfect but the next day they sent me a letter that they won't be moving forward with my application. The procedure is, upon successfully passing this preliminary test, they make a Skype video interview and then a 3-hour onsite assessment in their place. The negative side is you are responsible for all the costs of this travel.
