I am not certain why these are public accessible since these may lead to security leaks; for SEO purposes, perhaps⁉️

### Mail Exchange

Host seems down; perhaps the mail service is served under other domain name⁉️

## Questions about Job Descriptions

> Help our employees with in-person, remote and phone supports for their different HW and lighter SW support need. With focus on customer mindset.

* In-person means on-site, while remote and phone may be employees overseas or other Taiwan cities/districts⁉️
```
TW, Isreal (no IT), Korea.
```

* Could you be more specific on "lighter SW support need," such as what kinds of software are involved, what are the most frequently occurred issues⁉️
```
core apps; lighter means
access control, sw installation/reinstallation
```

> Assist establishment or integration of new sites.

No problemo❗️

> Solve first and second-level incidents and service requests from our service management system (Both Taiwanese and international users)

Please name a few service requests as well as the definitions of 1st/2nd-level incidents.

> Manage Taiwan telecommunication and IT vendor contracts.

Are/Is VoIP and/or VPN involved so to speak⁉️

* Provide Asset Management and manage user PC refresh need.

No problemo❗️

* Support network and server teams during changes to the infrastructure server/network.

Sounds fine by the general definition of "support;" rather than architecturing, since there's network and server teams already.  Under this circumstance, how does this position (IT Technician) collaborate with the teams.
```
Change control board
```

> Help colleagues in global service desk team with ad hoc task.

Please name a few "ad-hoc tasks," thank you.

> Conduct weekly/biweekly CCTV backup and database backup

For CCTV, are we talking about NVR or DVR; for database, are we talking about Oracle⁉️

> Microsoft Exchange、Cisco、LanServer、TCP/IP

Just wanna make sure: are Microsoft Exchange and LAN Server still in use in the organization as of today⁉️

## Others

1. [Google Meet](https://apps.google.com/meet/) as the remote interview solution is preferred; Microsoft Teams is okay, too.
1. A guided tour (on-site visit) of the site (working environment) would be nice.
1. Whom should this position (IT Technician) report to⁉️  Looking forward to discuss with him/her about the job details and how we can collablorate with each other in the future.

Primary GHW SW support in IT, end-user support,
