she is being 3 instead of 5 and reasons

I think 3w4 fits more than 5. At the beginning of the episode, we saw that Effy was not satisfied with her job. When she got home from work, she analyzed the reports instead of partying with Naomi, despite the fact that these reports had nothing to do with her job. This could be seen as the sign of 5; however, when she told to Victoria that the emerging market figures had not been updated, she did not get the reaction she wanted and it made her angry. After that, she asked Dominic to teach her all the trade works, and she used this knowledge to attract the attention of the investor. Thus, she got the job she wanted. Although she was initially good at her job, she couldn't maintain her success, as she acquired pragmatic knowledge about trading instead of having all the necessary knowledge. She had an idea of the reason behind the decrease of her shares, but she didn't care about the reason. Instead, she manipulated Dominic to use illegally obtained information and create treading profits. In short, all this seems to me as Te usage with an unhealthy 3. I thought she might be an ENTJ, but her Fi was still visible. Moreover, she was lack of Fe, especially in her relationship with Naomi.
