Booking.com da xar yili bo’ladigan Connect xaftaligi bo’lib o’tyapti. Xafta hackathon dan boshlandi, kecha hackathon tugagandan kegin CEO murojati, undan so’ng Lightning ⚡️ Walks bo’lib o’tdi. Lightning Walks dan maqsad boshqa departmentlarda odamlar nima ish qilishayotgani bilan tanishsangiz bo’ladi. Ularga o’zingizni qiziqtirgan savollar bilan murojat qilishingiz yoki ular qilayotgan ishga takliflar bo’lsa bu xaqida ular bilan bo’lishish imkoniyat beradi. Men o’zim bilmagan ko’p narsalarni bilishga imkon bo’ldi. Masalan skidka va bonuslar qanaqa ishlashini bilmagandim 🙃. Oldingi yili buday event bo’lmagandi. Event oxirida furshet bo’ldi unda siz kun davomida tanishgan odamlariz bilan ko’proq muloqat qila olasiz. Lekin meni suxbatlarim Argentinalik xamkasbim bilan bo’ldi. Yoshligidan beri saxmat oynarkan. Shunga men xisobda oldinga chiqa olmadim. Natija 2-1. Lekin bu suxbatni keyin davom ettirishga kelishdik. Bugun hackathon go’liblari va BBQ party bo’lishi kutilyapti.
