Huawei Technologies Senior Software Engineer interview questions

Was reached by a recruiter on LinkedIn. Had phone screen, coding interview on phone and was called for an onsite interview at Bellevue office. The interview experience was great. Was offered for this position and discussed the offer verbally, negotiated the better salary and the salary was agreed. However the offer was declined after two months by the HQ at China, There were super slow and pain to wait for months. This was the worst experience in my life till date.
