Another worst offender are security questions to unlock accounts. Answers to these questions are usually visible to customer service reps and similar set of questions are asked among different services. This is scary.
It's dangerous as having password stored in plain text as answers to the security questions can potentially unlock many other accounts.
I highly suggest everyone answers each of them with a unique answer.
What you said is true. Banks can always lower their transaction costs as they see fit(competitions) and beat BTC transaction fee anytime. So transaction cost might not be an advantage in such situation.
But people might still use BTC and pay up that extra cost because of its special property: true ownership.
Cheapest method:
Assume the government really want this number, they can have all mailman help keep track if there are leftover mail(a letter is created/given if resident has no mail) after x days.
Technology wise, I cannot think of an easy and cheap way. Camera with vision for each residential door will be a robust approach. Accuracy can be precise by more investment in software from detecting opening-of-door-event to facial recognition of the expected household members.
@OP: You sound almost exactly like me. I have not done any interviews for a bit more than 5 years.
I think the what really can be improved is to test us in a more familiar and friendly environment. I have to spend time on handling time-pressure, and fix/adapt with my thinking habits.
## Coding Problems:
I do think coding challenges(algorithmic) has merits, but I think there are two factor that really hinders a interviewee's performances:
- time limit
- require an unfamiliar algorithm
Time limit is obviously needed in a test, but problem solving in real life is never instant unless it's done before. Nevertheless everyone have their own pace. I have to dedicate hours each day to train myself to adjust my brain to act quicker yet calm for these algorithmic questions. Sometimes my initial solution in my mind turns out to be the best, but I discard it. Nevertheless if one is stuck, the time limit just makes it worst. I'm also known to be the slowest in turn-based board game -- I have high win rates though!
## Possible Solution?
* Allow interviewee pick from a pool of equally-difficult-challenges to solve (within a minute or two). This can solves the "obscure algorithm" or "trick" question. This also helps the time-limit problem as the interviewee WILL interpret the question twice in two different VIBES (with and without time pressure)
Even choosing 1 out of 2 would dramatically reduce nervousness and time pressure.
Everyone now with a smartphone can Pokémon game for free! This captures the previous market who grew out of it. Furthermore AR works very well with the Pokémon theme.
