2.  Why have you applied for this role?

I have applied for this role because the key responsibilities of role are [ 2, 3 key responsibilities from the job post] , and I have previously worked on similar roles with responsibilities [ 2, 3 key responsibilities from your previous experience]  , If you don't have prior experience then you can replace the above with ,  Some of my key strengths are [2/3 key strengths that require for the job and you possess].

4.   Tell me the most difficult task that you have performed recently.

Use your STAR : Situation, Task , Action, Result.

 Example: [S] we have recently launched our app in a new country,  the downloads were overwhelming but the conversation rate to sale was very less compared to other regions we have launched before, [T] I was given this task to investigate.   [A] I have spoken to a few users and quickly realized the UI was not that intuitive, so users are simply using services from other competitors.  I have communicated this internally and organized a plan to fix the problem and documented the learning for other regions. [R] This has resulted in a successful conversation rate dramatically and also we did not face this problem with other regions that we have launched. 

 

 

Debt recycling case study

 Debt recycling:

Debt recycling is generally one of the strategy for the people who wants to build wealth from debt effectively.    

When planned and executed properly  debt recycling can work in favour but its definitely not risk free thus it will not sure everyone.  Lets understand this in detail with a case study.

Case Study :

Tom is an illusionary person for this case study purpose with  Annual income of $100, 000.  Depending upon the country he is leaving he will have to pay tax on that income to the government.  For this case study purposes lets say the tax rate is 35%.

He bought a home with loan ( mortgage ) of $400, 000 5 years ago.   He is been paying around $2000 monthly repayments at an interest rate of 4% over 30 years.  He was also making significant lump sums payments during this period to reduce the over all debt and after the end of the 5 year period his remaining loan principal =  $250, 000. 

Tom has relativity stable job and mostly he manages his expenses pretty well and he decided to invest in shares with the view of achieving financial freedom in life. 

As like most countries,  Tom lives in a country which encourages investments with the incentives.  

One of which is : Tax deductible interest that is paid towards acquiring investments assets.   That means if Tom borrows $10,000 from a bank to invest in shares any interest that he is going to pay on this $10,000 is tax deductible.  

Tom has below options with money that he will have after paying all the bills ( and lifestyle expenses)  at the end of the month.

1. He could make additional payments into the mortgage

2. He could buy shares with that money to achieve his goal

3.  And here comes the third option .. Debt recycling .. 

First 2 options are fairly straight forward and in fact even the third one as a concept and theory is not that complex.  so what is that ? 

Debt recycling 

He pays additional savings into the mortgage and borrows money from the bank to invest. 

Ohh well , how is that helpful ? Here is how .. 

Tom has essentially reduced his non deductible debt by paying down his mortgage and borrowed money has deductible debt to invest.  Numbers ..

So the whole concept in a picture, 

Over the period , he could repeat this process to significantly built his asset column and also reinvest the profits ( after tax ) back into assets.  

So why not everyone is doing it ?

1.    The assets that acquired with the borrowed money has to produce significant returns/profits to offset the interest that he is going to pay on the borrowed money. 

2. Generally money borrowed for investments comes with higher interest rate and it is often require good serviceability.

3. Interest rate are not often fixed. if you choose variable interest rate, it could go up and thus the need for investments to produce more profits.

 Thank you so much for reading all the way through !! . Again this blog post is to explain my understanding of debt recycling and I am not an accountant and financial advisor. :).

ATF Parameterized Testing

Parameterized Testing within Automation testing framework is a feature that allows to run same Tests with different inputs thereby eliminating the need to copy the Tests. 

For example,  this feature comes handy if you wanted to automate the testing of a particular form.  the high level categorization of steps for it would be,

• Open form
• Fill fields
• Submit the form.

Once you have the above steps configured, you can define different parameter test sets using which the steps will run multiple times for different inputs into the fields.  

As of NewYork release, there is a limitation that these parameters can't be accessed with Run Server Side Step.

In this article, I will describe how to define a custom step to take the advantage of parameterized test at Server Side.

New Step Config:

• Navigate to Step configuration from left navigation menu and create a New Test Step Config

• Define input variable to this step to pass parameters from the step to the Server script, for this article I have created 2 input variables.

• Access newly defined input parameters in the Step definition script using the input object,  use these input variables as needed and define script as needed to process these input parameters

• Lets test the above step configuration definition, so lets create a new Test, I have also defined  Exclusive Parameters and enable Parametersing testing

•  I have created new Test step from the above defined Step configuration,  and tagged in parameters to the input variables.

 

Now the set up is complete, its to Test it with Test Data sets, I have defined the same and next screen to show the above set up has worked like a charm

Its not ideal to define a step configuration for each time you need to parameters at the Server Side but you can define a generic Test Config to club few use cases into one and also you can also define your input parameters as generic a JSON object and also another input param to pass script to be executed in the step config.  You get the idea.............

ServiceNow Major upgrade

ServiceNow every year releases 2 major versions and it is important to upgrade your ServiceNow implementation so that it remains supported as well as your organisation can benefit from the latest features included in the newer releases.


Based on the size of instance and customization generally a major upgrade cycle will take from 4 -8 weeks. 


Review the release notes and if you have sandbox instance available , use it for the first look and analyse upgrade impact on existing functionality and size out the efforts required to action the skip logs. 

ServiceNow docs site has 7-phase plan upgrade checklist Here is a good starting point planning the upgrade cycle.


The key points from the above checklist include:

1. Prepare project plan
2. Prepare test plan
3. Identify key stakeholders, power users, tests
4. Identify interfacing teams and environments
5. Identify the instances to upgrade
6. Agree on issue tracking mechanism

Dev/Test instance upgrade , shakeout , skip logs reviews:

• Clone prod over to DEV
• Upgrade DEV to targeted version
• Review and Action Skip logs
• Clone prod over to TEST
• Upgrade TEST to targeted version
•  Apply skip log decision update sets.
• Perform manual testing in TEST instance for the functionality where ATF does not have coverage
• Run Automation test framework
•  Track issues identified using ATF, manual testing

• Fix the issues

Tips:

•  Include audit data and attachments in the clone

• Use Check Now button on the upgrade Monitor screen if the upgrade did not kick in at the scheduled time.

Skip log reviews

During the upgrade process, if the system identifies a conflict, i.e the upgrade has an update to a file that has been modified by the customer,  it skips that particular file update and generates a skip log. Customers are responsible reviewing the skip logs and take appropriate actions.

1. Reviewed and Retained
2. Reviewed and Reverted
3. Reviewed and Merged
4. Reviewed
5. Not Reviewed

Reviewed and Reverted and Reviewed and Merged will modify the underneath application file, capturing these changes to the application file for the TEST instance promotion.

Tip : 

• Group these skip logs by priority and action the highest priority items first from the list.
• Make sure to right scope update set is selected while applying Review and Reverted, Reviewed and Merged decisions
• Use the comments field to capture rationale behind the decision.

for attachment in attachments:

obj = {

'attachment': attachment,

'number': numbr,

'options': options

}

tasks.append(obj)
