1. How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?

I would play by the book. I would delete inappropriate posts and handle issues that have been flagged by the community. Stack Exchange have good guidelines to follow in terms of moderation. Plus moderation is a team effort - Arduino SE already has a good moderation team as well as the wider moderation community.

2. How would you handle a situation where another mod closed/deleted/etc. a question that you feel shouldn’t have been?

Clear communication. They did that action for a reason. If the content is good but the post has issues, all the user has to do is resubmit the question/answer/comment without the problematic part.

3. In your opinion, what do moderators do?

Moderators deal with the daily issues which allows the Stack Echange to run smoothly for its visitors.

4. A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light. How do you feel about that?

I'm not bothered. I treat every post/comment/answer/question with respect.

5. In what way do you feel that being a moderator will make you more effective as opposed to simply reaching 10k or 20k rep?

I would rather gain the reputation. :)

I am not going to be the best moderator out there but I will try.

1. How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?

I would invite him to focus on what's most important and how time and energy consuming conflicts can be. He is a great contributor and he can create a better image of himself by just avoiding flaming others.

2. How would you handle a situation where another mod closed/deleted/etc. a question that you feel shouldn’t have been?

I would contact the mod to understand what I might have been missing.

3. In your opinion, what do moderators do?

Help in maintaining the topic efficient, both in terms of results quality and speed: prevent non-related content to slip in, avoid or stop flame wars, prevent unanswerable questions to appear to the user base, and so forth.

Proud but also scared: I will no longer represent only myself and my actions will reflect on people I don't even know.

5. In what way do you feel that being a moderator will make you more effective as opposed to simply reaching 10k or 20k rep?

In absolutely no way: it will only imply a greater responsibility.

**UPDATE

A few additional questions came up.

How would you handle this hypothetical situation? A user with less than 50 answers in 75 months continues to excessively self-promote (arduino.stackexchange.com/help/promotion) and tries to sell you his products in more than half of their answers. What would you do about it?

If the answers are on-point I see non reason why I should moderate him. On the other hand, if his answers are misinterpreting the question (either voluntarily or not) I would give him a warning. If he keeps promoting his stuff outside of the question topic I would report him for a temporary ban, possibly turned into permanent if things don't get right.

As of 2021-07-08 PST, we have 3 candidates. When I compare Juraj, sa_leinad, and Roberto Lo Giacco's profile & activity data, it's crystal clear that sa_leinad, and Roberto Lo Giacco have done very little in the past 63 months in the way of editing, flagging, and up-voting. Why, all of a sudden, do you want to be a moderator when the data shows you have not been putting in the work that will be required of you as a moderator?

This was the toughest question. I'm a busy person and I cannot guarantee I will be able to put much more time into moderating, but I thought even the additional 1% could be helpful. If it comes between me and someone else having the possibility to invest more time, then hell yeah, scratch me out and go for him/her.

I honestly have no need to become a SO moderator, but SO gave me a lot in these years so I thought I should have at least tried give back something, probably not enough, but better than nothing.

Was my thinking wrong?

Another hypothetical question. You are elected as a moderator, then you discover that one of the moderators has done practically nothing in the past 2+ years. The other moderator has handled 99% of the flags, post closures, in other words, "work". How would you feel about doing the required tasks for a moderator who refuses to do any "work", but retains his position?

I would ask the other moderator to step down and give up his position in favor of someonelse who might better help the community.

1. How would you deal with a user who produced a steady stream of valuable answers, but tends to generate a large number of arguments/flags from comments?

Why this question? I didn't see this kind of problem on Arduino SE or Stack Overflow. Any longer comments exchange is moved to chat.

2. How would you handle a situation where another mod closed/deleted/etc. a question that you feel shouldn’t have been?

First I want to say it didn't happen here that I would feel a moderator shouldn't take some action except of declining my flag one or two times. I asked about it (on Meta) and I got an acceptable answer. If as a moderator I disagree (very strong) about an action of other moderator, I hope there is way to talk to other moderators and express the disagreement and hope for explanation, but I will not start an argumentation fight or revert the action myself.

3. In your opinion, what do moderators do?

Moderator's mission is to guide the community. Users better accept instructions from a diamond moderator.

Moderators duty is to handle flags: flags on Questions, flags on comments, flags on Answers.

Moderators can close/open/delete Questions immediately if there is a good reason to do it. Moderators can migrate Questions to other SE sites and accept migrated Questions.

4. A diamond will be attached to everything you say and have said in the past, including questions, answers and comments. Everything you will do will be seen under a different light. How do you feel about that?

I like it

5. In what way do you feel that being a moderator will make you more effective as opposed to simply reaching 10k or 20k rep?

On Arduino SE all useful community moderation privileges are achieved at 4000 rep points. I reached that in September 2018. I use the with privileges available moderation tools.

As moderator I will take action instead of flagging.

If 3-vote closing stays, then there will be less work for moderators to maintain Questions, but some off-topic question would be better to close sooner than required count of votes is collected.

I would like to migrate more Arduino specific Questions from Stack Overflow and EE SE. Maybe as moderator here, I can do it more efficient.
