Haha - whiteboard firing squad - I like that. Thank you for the offer to do a trial interview. I really appreciate that! Let me see how this week interviews go, and I may take you up on that. As opposed to failing 2 out of 2 whiteboard inte

Yes, starting with a brute force solution is a good advise. That paid off for me a couple of times. I need to keep reminding that myself - sometimes I get carried away trying to jump straight ahead to something more optimal.

Yeah, that would require a whiteboard and a programmer friend who is kind of enough to endure the misery of watching me struggle with a marker, trying to remember how to write by hand again.. I have very little experience interviewing (my p

Yes, I think that will help. For me personally it is also helpful to be able to analyze the problem by myself, without having to talk through it. Being able to write some code in an editor is also helpful as it springs my brain into action.

Just wanted to share another thought about protection from bots. In my tests, I didn't get any retweets from bots or other fake accounts. I think it is because iOS promo codes don't have any tangible value to a bot operator. You c

That's what I thought, only most recent timeline counts. From my experience anything older than 15-30 minutes is not noticed anymore. So I agree, that's a good amount of time to use as the grace period. Just intuitively I think pe

It is not for everybody, that's for sure. But if you want to run a giveaway of iOS promo codes on Twitter then you'll see that it is kind of a tedious task. You need to constantly check who retweeted your tweet, get a new promo co

Thanks! I built it because I wanted to use it myself. You can read more about pricing here: https://www.productpush.io/pricing Essentially, i wanted to have per usage fee people would be comfortable paying instead of doing

I thought about this possibility actually. At least for my apps I only get retweets from real users. In future, I can try to implement a combo of: a) Flat campaign fee with no charges for retweets. So you won't pay for bots. b) Send a

That's true. But my service doesn't detect the retweet right away. So it has to stay retweeted for some (currently about 1 minute) period of time. I can tweak this parameter in future if I see that users misuse the service and und

That's a good point. Thank you for the suggestion. I guess I'm a bit naive not thinking about this right away. :) Not sure if it is fair to only count retweets with 100-200 followers though.. Plenty of novice Twitter users don&#x2

That's right, it can deliver any "string" as a reward. I personally only needed to deliver iOS promo codes, so it seemed like the most useful application to me.

I was surprised how much the article resonated with my personal experience. I too had anxiety attacks and ER visit fearing it was a heart disease. Many (too many) doctor visits later, here is what works the best for me: - Exercise. Can not
