ZTE Huawei's after-sales and pre-sales technical support

I have been engaged in the software industry for many years, and frankly tell you: there is much more room for development before and after sale, and it is also more challenging and fulfilling; After-sale is more important for a company, but most of them are annoying and cumbersome. ZTE and Huawei are both very good, but if I have to choose one, I recommend Huawei. Personally, Huawei is better. Huawei is really strong. Although Huawei works more overtime, friends who work in Huawei say it is much better now.

So I recommend Huawei to pre-sell.

As for what to prepare, in fact, large companies pay more attention to comprehensive ability, quality and responsibility. Pre-sale is a post that embodies comprehensive ability, which requires technical ability, professional knowledge, industry knowledge and communication ability. It is not necessary to prepare deliberately and adjust the mentality.
