Should I use robo advisor Essential portfolio on Ameritrade.com?
May 29, 2019
It is my personal finance research. I like to learn how to hold growth fund and learn how to rebalance every quarter if need. One idea is to open an account and put $5,000 US dollars of my IRA and let Robo advisor to do the work.
I like to learn how to do rebalance the portfolio and understand the market, my time horizon, and risk tolerance and my finance goal. One of ideas is to open an account on Essential portfolio on Ameritrade.com.

Case study: My portfolio
May 28, 2019
It is time for me to come out the portfolio of IRA Ameritrade account. I have around $16,000 US dollars right now, I just bought BND ETF two weeks ago, I need to figure out how to set up a portfolio for long term growth.
I like to work on $12,000 fund and plan to purchase VTI, VYM, VGT, VUG four ETF.
VTI 20 shares x 143
VYM $84.13 * 40
VUG
VGT $197.81 x 20

Case study: Mock interview on lowest common ancestor
May 28, 2019
I had a mock interview 10:00 PM today. I asked the interviewee to work on the algorithm called lowest common ancestor, and it turns out that he is super good engineer and very good problem solver.
The interviewee just showed me how good he was to solve the problem, and also worked on extended problem.
I will add more content here later.
